I'm running CentOS 5.3 x86_64 on my laptop (dell vostro 1400, core2duo, 3GB RAM, intel 3945ABG wireless, nvidia video and LAN). The problem is that some times (like 15-20% of times) I shutdown the laptop, I get a kernel panic related always to the wireless kernel module (I haven't been able to get screenshot or anything). I'm using the latest centosplus kernel. I never get these panics with the standard CentOS kernel, however the standard kernel doesn't light the wireless led, and that annoys me a lot. Therefore I'm forced to use centosplus kernel. The question is not how to solve this (i know I've not given enough details) but what to do to diagnose better the cause of the panic and then correct it.
I have this weird issue which only appears when I am using 64 bit Ubuntu. Every now and then my laptop seems to go into a kernel panic (system unresponsive, numlock and scrollock lights flash repetitively) only when I am using the broadcom wireless. I can connect to my wireless router and use the internet and local network, but eventually, kablamo, crash, bang, boom. The only way out of the crash is to power off completely. After repowering, the wireless network is fine until the next crash. There does not seem to be a pattern or time period to cause this crash either. I have purged network manager(which I couldn't get to use my wireless) and am using wicd, which allows me to connect wirelessly.
I'm trying to use and old Dell Dimension 2350 workstation with 1GB of RAM and a 200GB drive as a home server. I boot the CentOS 5.3 install DVD, get to the splash screen and hit ENTER to start the install. The install routine starts and then kernel panics with a very long trace I can't make sense of. I've used the DVD for other installs so I know the media is good.Are there any known quirks to installing linux on a Dimension 2350? Maybe some kernel line parameters like no acpi?? As a test, I took an Ubuntu server cd, and the install actually completed but on reboot it kernel panicked with a similar long trace error. Obviously this is most likely a hardware issue.
Recently switched my home server from Gentoo to CentOS and have been getting kernel panics consistently since I made the server "live". The machine was built with all new hardware. I'll post relevant configuration info and picture of the kernel panic below. So far all kernel panics have been with kernel "2.6.18-164.9.1.el5.centos.plus", right now I am testing with the kernel listed below to see if it does the same thing (2.6.18-164.9.1.el5).
I just built a computer with these specs: Asus P7P55D-E Pro Mother Board 2 x 4gb GSkill RipJaw 1333 Intel Core i5-760 cpu MSI nVidia GeFore GTX-460 Video Card
When I try to boot from a live CD/USB I always get some sort of kernel panic, most times about USB controllers and other times about cpu_idle. I have pictures of these that I can post but nothing from any logs because this is happening even before I install. I have left memtest running over night for 11 hours and had no problems, I have tried to boot with only one stick of memory, I have changed the video card to a GeForce 8800 and I have tried everything on a different motherboard and still no luck. Would I wrong to say that there is a problem with the CPU and should I return it? My only problem with all of this is that Windows installs perfectly fine on the computer with zero problems...weird.
I have been a happy Ubuntu and other distros user from 2007 to now. Had my old 7.10 Gutsy Gibbon (Ubuntu Studio actually) that I really felt was time to upgrade. Then I downloaded the ISO image for 11.04 Natty Narwhal past 4 day ago. It gave me an option to install on my old 7.10, upgrading it, then I chose that one not to have to lose my data.
At the very end of the installation (when downloading several packages from the net) I got a kernel panic. After that I reinstalled from zero wiping the whole partition, with the same results. It only worked when I disconnected the net cable so it wouldn't download anything during install. Then I could run the 11.04, but kept getting kernel panics, and after some testings (I thought it was the nvidia video drivers at first) I think it happens after some ammount of network traffic happens.
Memtest went normal, I tried logging with no-effects and I tried some solutions from forums with no results. The pc can be on and working for hours, but after I start surfing the web for some time, I get a freeze. Sometimes Caps Lock and Scroll Lock leds are flashing, and sometimes just freezes to simply become unresponsive. When it was during the installation I got a message saying it would pop out into console because panic occured and then froze. Anyway I always have to press the reset button.
I would like to be sure if I have some of my hardware broken or if the newest kernel is still green on some hardware support; maybe network. I'd also like to know if I can install older versions of the kernel; I think that should fix the problem because other distros worked perfectly here before. I also heard about some kernel-image-pae being different from the ordinary kernel image. Could it help if I change that package? I'm waiting to install 11.04 in my wife's computer also but of course I don't want to bring any problems on her! My net card is Nvidia Nforce and my processor is AMD Athlon II X2 with a GForce 9400 for video card.
My friend's PC recently started acting up. He had me install Sabayon on it and everything was fine until a few days ago. Every app I try to run after the PC boots results in a segmentation fault. I figured maybe something was wrong with the HDD, so I tried to boot from a DSL liveCD to run fsck, but it wouldn't boot; it freezes right away. I then tried the Sabayon LiveDVD and got a kernel panic.Does anyone have any idea what the problem could be? I am completely clueless; I've never had anything like this happen before.
After building a new system I have been getting kernel panics randomly. I have been able to look at /var/log/messages and determine that either my RAID card, XFS, or something along those lines is causing the problem. It has now gotten bad enough that any heavy use of the RAID will cause it to panic and die.
There is one large file on this that I need which is not on my backups but when I try to get it off, the transfer will cause a kernel panic within minutes. What is causing the panic? Is there any way to resolve it? The RAID card is an LSI SAS3081E-R and I am using the built in drivers/modules within Ubuntu 10.04 x64 (pretty sure the kernel itself has the driver included). There is source available for the driver from LSI's site but I'm not sure if that will solve the problem and in addition to that, I can't figure out how to compile and install it. It has a Makefile already but make just complains "no targets".

I've been trying to install fedora 12 on my laptop, however, I've been running into kernel panics on both the live cd and the install dvd. I'm using an HP HDX16 with an Intel Core Two Duo T9400 @ 2.53ghz, and a Nvidia Geforce 9600M GT. Dunno if any other hardware might be involved. Here's the text I get on my screen:

Since the update to 11.3 i'm getting kernel panics randomly. Because the X server freezes and I can only force an "unexpected reboot", there is not much information I have. I installed kdump and activated it with the Yast module. I'm collecting dump files, now. But I'm not sure what to do with does files.
F12 Clean Install stopped with line: [<c04041a7>] kernel_ thread_helper+0x7/0x10 The machine has completed more than 30 hours of HD cleaning with DBAN (overwrites the HD). It used to be able to run F9 or Ubuntu 8.04 but always returned kernel panic during other distro installation attempts. Why after a complete HD clean though?
I have loaded openSuSE 11.4 on an IBM x3400 box with an Adaptec ServeRAID 8k-l SAS harddisk adapter. openSuSE 11.1 was previously loaded on this box and was using XEN kernels.) The default "desktop" kernel boots and operates correctly. I use this machine to run other XEN virtual machines to run different versions or our companies printer controller application. When I attempt to boot the xen kernel, the kernel cannot locate the root partition (or any other partition) on the hard disk. Here are a few lines of kernel output:
A while ago, when I was using Maverick, Firefox started to crash randomly and led to kernel panics.
So I upgraded to Natty (clean install) and Firefox there too crashed.
Then I was getting graphics and make problems.
Today I tried to install Fedora 15. It first boots to a Live desktop that warned me that my hard drive had 65000+ bad sectors. Sixty-five thousand.
So I got a new one. A WD Scorpio Black, 750GB 7200RPM with Advanced Format.
Again I boot into Fedora 15. OK, no bad sectors. I tried to run Disk Utility Self Tests but it constantly crashed. Fedora warns you about this.
In the Live session, I opened Firefox. It also crashed just like back in Ubuntu. Then the screen flashes black and got warnings after warnings that a kernel module has crashed.
So I took out my old Maverick installation CD and first tried a Live session. However, Disk Utility told me that SMART is not supported while on Fedora, it was.
So I tried to install. But soon after that, I got a warning that the installer has crashed because a file copied to the disk did not match the file on CD. Right now I am in the Maverick Live session.
Every time my wifi auto connects it gives me a strange message:
At the same time it makes a new network entry, overlapping the one previous:
It's usually a battle with the wifi and my re enabling the correct setting over and over and over again. Is there a fix for either the mysterious lack of selection in the first message, or a way to force it to use the correct one without making another?
When trying to install RHEL 5.4 on a Flagstone SATA (encrypted hard disk), linux timeouts while loading the ata_piix module.
ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata2.00: cmd 81/00:08:00:00:00/00:00:00:00:00/e0 tag 0 data 4096 in res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata2: soft resetting port ata2.00: configured for UDMA/33 ata2: EH complete
The above message is repeated several times until the kernel eventually "panics".If I use a non-encrypted SATA (Maxtor, Fujitsu, etc), the install works. It only fails with Flagstone SATA encrypted hard disks.
Building an nVidia driver requires sources for the currently-running kernel. In my case (Fedora 12), it is, according to 'uname -a', 2.6.31.5-127.fc12.i686
I thought I could get the sources with 'yum install kernel-sources', but there is no such package. Then I tried 'yum install kernel-devel'. That package exists, but the kernel is 2.6.32.9-67.fc12.i686
I want to boot into a new kernel like 2.6.34 over the default 2.6.18 RH/centos kernel. i know you cant copy the .config file and use it since there are so many changes so what is the best way to compile the kernel and get the right settings?
I'm on an Acer Aspire 7535 Laptop running a dual boot with 10.10 and Windows 7. Although a fresh install of Ubuntu 10.10 doesn't seem to give me any problems, after a few updates, my laptop would lock up and give a black screen while using 10.10. The kernel panic seems to happen randomly, either taking minutes or hours to happen, whether I am doing anything or idling.
I have had a serious problem with my laptop recently. I have been having unexpected reboots and kernel panics and I don't know why. I can't tell if it is hardware or software, and what is causing it.
It has happened on multiple power bricks from different outlets and locations, my slice battery and my main 9-cell battery.
I am running Debian Testing/Stretch with Kernel 4.1 with XFCE4 on a Lenovo T420 with 16 gb of ram, a i5-2540m, USB3 Express Card, OCZ SSD, an intel 7260 ac wifi card and Ericcson F5521GW 3g card. I also have a modded bios for the wireless cards, and I have had that for over half a year without any problems.
I have no clue what the cause is from the logs.
I also booted into Windows for a bit, then it blue screened, but I don't know if it was because of a driver I had tried to put on earlier for the 3g card, because Linux was out of commission and I needed 3g. The driver didn't work, gave a code 10 or something and gave me a blue screen that said something along the lines of device driver attempting to corrupt the system has been caught. Windows also won't boot anymore.
I'm not worried about Windows though, and what I really need is Linux to work, being that this was the first time I booted up into windows in several months.
Memtest runs fine, and passes all tests.
Right when I turned on my computer after one incident, I wrote a script to check the CPU temp and write it to a file every second. Once the computer turned off, I read the file and it said the CPU was at 39 degrees. Not something to turn off over.
I cannot find any indication of a problem in /var/log/kern.log. kern.log was extracted from the computer right after it rebooted randomly. Find it here: [URL] ...
I am using Ubuntu Lucid Lynx 10.04 (64 bits) in my Asus U30JC laptop (Core i3 M350, intel 4500MHD + nvidia 310M with nvidia Optimus, 4GB RAM). I am content with Lucid and I don't want to upgrade to 10.10 for now. However I read that the new 2.6.36 kernel has some good improvements, such as improving system interactivity while intensive I/O (such as copying large files), and improved energy management for i3/i5 processors (which I hope translates into more battery time, which is a problem of Ubuntu vs Win7 in my laptop).
I discovered I had 2 options: compile the kernel myself, or use the Ubuntu Kernel PPA (maintained by the Ubuntu Kernel Team). I decided to use the PPA, so I added it to my software sources and installed the generic"linux-lts-backport-natty" kernel (2.6.36-1).
Package installation went fine, and after reboot, I could log in to the desktop no problem. Everything seemed fine, but after a few minutes, the system freezes completely: mouse did not move, none of the indicators moved, even Ctrl + Alt + F1 did not work.Where is the log file where there might be a message related to the freeze? Do you think that the kernel developers would try to fix a bug that probably only affects people running the 2.6.36-1 kernel on a distribution that was not built around it?
I have an IBM server with a: "SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07)", meaning kernel module CONFIG_FUSION. This is the real hardware, not emulated by vmware. With recent kernels (2.6.30-35) the boot results in one of three situations:
1.) Most common: kernel panic, way too long stack dump to see anything useful but did have a terminal briefly to debug this and its just not being able to communicate with the scsi subsystems, google for errors found nothing of use.
2.) Sometimes: A hang waiting for the scsi disks after the controller fails to initialize properly, does not pass in a couple of hours.
3.) Very rarely: A long wait for the scsi controller to initialize but a succesful boot afterwards. ACPI subsystems are taking all CPU power. This is the state the machine is at now, working somewhat.
I can boot the machine with a Gentoo live install disk (kernel 2.6.29 I think) and under that version the controller initializes instantly and there are no problems whatsover using the disks so the hardware seems to be solid!
There were some MPT changes in 2.6.25rc5 so thats the latest kernel I've tried. The errors during boot change to a bit more verbose but thats about it. Unfortunately I don't have a serial terminal with me anymore so cannot capture these errors but it was something about an "unexpected doorbell" with 2.6.24 and nothing memorable with .25. Long story short tho, googling the errors provides no solutions and the little I find points to the controller being too slow to initialize somehow.
I'm running out of ideas here and the server is burning fans like theres no tomorrow (ACPI taking everything it can) so is my only option to downgrade to 2.6.29 (and downgrade udev, lvm2, so on and on and on)? I can't believe I'm the only one for whom this has been broken for several minor versions.
Kernels tried:
- 2.6.29-gentoo (live disk) - works, blazing fast initialization - 2.6.32-gentoo-r7 - random boot failures and successes - 2.6.34-gentoo-r1 - same - 2.6.35-rc5 vanilla - same, better errors, zero useful google results.
I'm not very keen on longshot attempts since it can take a couple of hours of panic-loops to get the machine booted up again and the server functions cannot be transferred to another machine. Also, I'm a bit hesitant to mention this, but the boot has only ever succeeded when a serial cable with something at the other end is connected. At first it was the testing serial terminal and now its just a connection to a UPS.
Attached: bootlog of succesfull-ish boot with 2.6.34 (had to cut some out to make the sizelimit):

I'm having a strange problem on some of our Debian servers. It all started about three weeks ago when we moved our virtual environment (VMWare ESX3) from a SAN to a NAS (NetApp). At first I thought it had to do with that move but since the other 9 servers are working perfectly I eliminated that idea. For over a year all 12 Debian 5 servers have been working great without mentionable failures. All servers are (where) up to date with the latest patches. About three weeks ago I started having kernel panics with the following message on three of our servers:
Code: Code: Bad EIP value EIP [00000000] 0x0 SS:ESP 0068:f6d7da18
Kernel panic - not syncing: Fatal exception in interrupt and other times it looks like just a dump of hexadecimal data. The only difference between those 3 servers is that they have several mounted shares connecting to the NAS using CIFS. So I was thinking that it might have to do with an update of some kind in regards to smb. I recovered an image from a month ago, before the troubles began, copied over the data and MySQL databases and configured the 'old environment with recent data' exactly the same with MySQL master-master replication, document synchronization and load balancing. This task I performed last night (no other way since it's a production environment). Up to this time neither of the two 'restored' servers had a kernel panic. The one that has not been restored is having one at random about every hour and a half. Following are the different versions between the 'at this time' working server(s) and the failing one:
I am running a headless Ubuntu 10.04 server with the 2.6.32-28-generic kernel. For what I can figure out no single direct cause I get a high load average and the following syslog output at random intervals. Generally the load average will drop back down to normal however the kernel errors will still continue What little I have been able to find has pointed to memory issues. I am not totaly convinced this is the cause as the server will be showing >50% free when the errors are happening.
Where a CentOS 5.3 installation on a server randomly restarts. The problem is that I am not able to find a viable solution. I have updated the system to the latest available kernel, but to no avail...
The output I see in /var/log/messages when the restart occurs is very similar everytime:
i am getting duplicate entries in dag rpm repository with different names in different cases !
# yum search fileinfo php-pecl-Fileinfo.x86_64 : Fileinfo is a PHP extension that wraps the libmagic library php-pecl-fileinfo.x86_64 : PECL package to get file information through libmagic[code]....
I upgraded my OS from 5.2 to 5.3 through the system built-in updater. Then I found that I lost correct SCIM support for some applications. I was able to type Chinese and Japanese into aMSN and Skype when it was CentOS 5.2. But I can no longer do that now. Typing into some other applications still works. These applications include sylpheed, firefox, and open office....
The last time I did a restore using cpio under CentOS 3.9 it took a very long time for me to find my seemingly correct command wasn't working and I ended up doing the work in Knoppix. This time I thought I'd run my command by wiser heads before the necessary tape turns up and I spend a lot of time finding my command doesn't work. cpio -i -mtvV --block-size=128 --no-absolute-filenames /var/log/maillog* < /dev/st0
