General :: Kernel Panics - RAID Or XFS Related?

Jun 21, 2010

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".

General :: App Segfaults Every LiveCD/DVD Kernel Panics?

Jan 23, 2011

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.

Ubuntu :: Getting Kernel Panics While Booting From LiveCD / USB

Feb 17, 2011

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.

Ubuntu :: Kernel Panics In Natty All The Time?

May 10, 2011

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.

CentOS 5 :: Install DVD Starts And Then Kernel Panics

Apr 29, 2009

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.

CentOS 5 :: Random Kernel Panics / Correct It?

Jul 8, 2009

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.

Fedora Installation :: Kernel Panics On Both LiveCD And Install DVD

OpenSUSE Install :: Update To 11.3 And Getting Kernel Panics Randomly

Jul 22, 2010

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.

Ubuntu Networking :: 64 Bit Bcm4311 Wireless Random Kernel Panics?

Sep 22, 2010

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.

Here is the details of my system:

Dell inspiron 1520
lspci (snipped)
0c:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

OpenSUSE Install :: 11.4 Xen Kernel Aacraid Drive Panics With Adaptec ServeRAID 8k-l

Mar 28, 2011

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:

Ubuntu Installation :: Firefox Started To Crash Randomly And Led To Kernel Panics

Aug 2, 2011

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.

Fedora :: PAE Related - Kernel Versions Are Different In Two Folders?

In the processing of reinstalling VirtualBox, I found this: -> /usr/src/kernels/ ,but this folder don't exist.。 I try to relink the ln as source -> /usr/src/kernels/ , but VirtualBox still get problem with the kernel. Since VirB works fine with other 2 kernels, the solution for this is not quite needed, but I just wonder why this happens. See below. I don't know why these two folder contain different version of kernels. Anybody get an idea?]$ ll /usr/src/kernels/; ll /lib/modules/; ll /lib/modules/ |grep build

Hardware :: Ata_piix Timeout On Flagstone SATA / Repeating Error Until Kernel Eventually "panics"?

Apr 9, 2010

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

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.

General :: Shutdown After Swap Corruption (or Something Related)?

I have a box that has been running fine for a few years primarily as apache/tomcat/mysql server.Just recently, it has started spitting out a bunch of messages and shutting down.The computer is running FC11, x86x64.If anyone can glean anything from the messagesIf you need any more info, let me know. I can get someone to start it up, and get as much as I can before it crashes.From looking at the messages, it seems like it could be something going on with the swap, but I'm not sure.The messages are below.(The box is on the other side of the country from me, so I don't have a ton of info, and it's hard for me to get someone to physically restart it for it's kind of a pain.)(You'll see a lot of errors related to SSHD. I don't know if that's because SSHD is the culprit, or if it's because I was connected using SSH. For some reason I'm leaning towards it being something other than SSHD.)

Ubuntu Servers :: RAID-5 Recovery (spare/active) / Degraded And Can't Create Raid ,auto Stop Raid [md1]?

Feb 1, 2011

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.

Now the array is (logically) no longer able to start:

mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]

I was able to examine the disks though:

root@ mdadm --examine /dev/sdb2
Magic : a92b4efc
Version : 00.90.00

mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.

Fedora :: Raid Not Auto-starting After Kernel Update

Jan 25, 2010

I updated my fc12 x86_64 server today, and one of the updated included kernel from the previous one of kernel- I boot with that kernel, it stops when my logical volumes that are built on a raid 5 array (linux software raid built using mdadm) are not there.I can start them afterward with mdadm --auto-detect which seemingly loads the appropriate modules and starts the array, but I have never had to do this before.

Reading the mdadm man page, it mentions that this is generally done by the initrd. So, I am guessing the initrd that came with the new kernel is missing something.

Fedora :: Failed Boot With Kernel And SW RAID Volumes?

Apr 24, 2010

First post so please excuse my lack of correct terminolgy/understanding/etc. Running Fedora 12 with the following software raid setup...

Mount Device Underlying Partitions
/ /dev/md0 /dev/sda1 /dev/sdb1
swap /dev/md1 /dev/sda2 /dev/sdb2
/home /dev/md2 /dev/sda3 /dev/sdb3

Recently updated to kernel and upon restart, failed to boot. Get stuck at a recovery prompt asking for root password or Ctrl-D to continue (which reboots system). I worked around this problem by reverting to the previous kernel From what I can tell, with the newer kernel there is a problem with device enumeration of software raid volumes.

Ubuntu :: Transmission Causing Panics Every 2 Minutes?

Jan 26, 2010

Is anyone else having trouble with frequent kernel panics whenever the Transmission bittorrent client is running? I get them after about 1-2 minutes of having transmission running, and need to do a hard reset. I didn't restart transmission this last time and it has been almost 10 minutes with no problems. I've been having problems left and right with KPs since around 8.04 but previously they were infrequent enough that it was still more convenient than using windows...Every 2 minutes is ridiculous though, if I can't fix it I'm going to need to get another torrent client!
