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.
View 2 RepliesI 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 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.

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:
Code:
FAILINGWORKING
samba-common 2:3.2.5-4lenny122:3.2.5-4lenny9
smbclient2:3.2.5-4lenny122:3.2.5-4lenny9

Is there any way to get openSUSE 11.2 to automatically shutdown or hibernate when the laptop is overheating? I often cannot tell when my computer is overheating as it sits on a table. When it over heats, the kernel panics and I have to hold the power button to force my computer to shut off.
View 4 Replies View RelatedI have been experiencing some random log out, specially in times like downloading big files, and consequently messing up my downloads. It's like browsing internet, a few other applications opened an out of nowhere a black screen an command boot load and then log in screen asking for password. This has been happening since I installed natty. I experience any kind of crash alert, freezing or slowdown before it happens, just out of the sudden it happens.
Any advice, help? How do I report a bug without a clear idea of what's going on?
I have recompiled a few kernels, but all on 32bit systems so not sure if that has anything to do with it.
Running Arch Linux 64bit, most recent version.
Kernel Output:
Code:
My first thoughts was that it might be my grub bootloader configuration, so had a big play around with that but it didn't fix it. Also made sure support was built for filesystems. However almost all that Fstab mounts are ext3 anyway, and certainly the root and /boot are. Now thinking it may be a memory error so will run a check when I shutdown.
Dell laptop booting from a USB stick with a CentOS 5.5 minimum installation.
Uncompressing Linux...OK, booting the kernel.

sda: assuming drive cache: write through
mount: error 6 mounting ext3
mount: error 2 mounting none
switchroot: mount failed: 22
umount /initrd-dev failed: 2
Kernel panic - no syncing: Attempted to kill init!
1. Does minimum installation not drop on a kernel or initrd with ext3 support? I can't imagine that's true, but have to ask.
2. The USB stick is single partition ext3. Maybe there is some limitation specifically related to USB stick booting that requires boot to be FAT16 or FAT32? Except the CentOS 5.5 installer refuses to let me install on either FAT.
3. How can I do the equivalent of lsmod on a linux installation that will not boot? i.e. I have CentOS x86_64 running in VirtualBox, I can plug the USB stick in there, so how do I get information on the USB stick's kernel and initrd if I can't boot from it?
4. Is it possible to rebuild the i386 based initrd on this USB stick, when the computer is not booted from that stick, with a system that's x86_64 based?
System Info:
Dell Latitude i686 Laptop which has run CentOS 5.5 and Fedora 12,13,14 in the past, and boots from Fedora 14 Live CD transferred to a USB stick. So I know USB booting is possible on this machine, and this stick.
The process of creating the stick:
CentOS 5.5 i386 on a USB stick. Old Dell i686 laptop which has previously run CentOS 5.5 installed from DVD, and has successfully booted from this same USB stick holding transferred Fedora 12,13,14 Live CDs. CentOS 5.5 was installed onto the USB drive directly by the CentOS 5.5 DVD installer (running virtualized in VirtualBox 4.02 on Mac OS X 10.6.5.). No errors or complaints during installation.
For whatever reason, the installer did not do some things correctly. First Grub wasn't working correctly, I got that sorted out and have the Grub+CentOS splash screen, it finds vmlinuz and the initrd, and then I get a kernel panic.
Ext3 was built into the kernel and that's why I'm getting this message. I do not know how the installer would have dropped a kernel or initrd during instalation that that don't contain such a basic thing that obviously comes in linux kernel 2.6.18-89 EL.
I have the following strange thing with a RHEL4 installation. Since last week, the system did a reboot and now something is really fucked up. During boot we get the following messages (don't care about 'strange' typo's, my colleague typed it 'blind' from the screen)
Code:
The strange thing is that we never see a 'could not mount blabla' or similar messages. First we thought it was a failing kernel update by plesk, but even after manually updating the kernel with RHN RPM's, still the same message. Booting with rescue mode and then chroot the system works. After that we even can start things like plesk and so on.
We double checked things with another RHEL4 install, and at least two things were odd:
1: the working machine has /dev/dm-0 and /dev/dm-1, the broken one doesn't
2: some files on /dev didn't have group root, but 252
We tried to recreate the /dev/dm-X nodes with [vgmknodes -v], output:
Code:
A fdisk /dev/sda shows: /dev/sda2 XX XXX XXXXX Linux LVM (I removed the numbers because this line is from another machine, but rest was identical)
We have a copy of the boot partition so if one need more info please let me know.

I restarted the computer and when I tried to enter my operating system I got this error "Kernel panic - not syncing : VFS : Unable to mount root fs on unknown - block(8,1)"
I have previous versions of Linux on my computer so I can still get in to those if need be but I don't know how to undo what I did or why it isn't working for that matter. Does anyone have any ideas as to why I am getting this error and how I can fix it?
I have one machine where I have several versions installed on different partitions. The base partition (/dev/hda1) is Slack 12.1. On a spare partition (/dev/hdc4) I had installed Slackware64-current. Last week I slackpkg upgraded and installed the 2.6.32.2 kernel, and now that partition will not boot. I know that with the new kernels the hd* designation has been removed, and have already redone that fstab (accessing it from a different boot) to reflect the sd*. Here is the slack64 section of my lilo.conf:
Code:

this is what i did i downloaded the latest stable kernel archive from kernel.org and extracted the archive into the download directory (i don't think that matters though) then i downloaded and installed the ncurses archive (needed for menuconfig) then i opened a terminal and navigated to the directory that was extracted from the archive and issues the floowing commands

Keep having random freezes on my laptop.. Its a Dell Stdui 1558 running Ubuntu 10.10 however i dont get the freezes on 10.04.01
So i might have to revert back to 10.40.1 #
I have a CR-48 running Ubuntu 11.04. I've had some continual issues with it, along with other Linux distros I tried. There are times my laptop freezes completely during mid use. If I power off and back on, 70% of the time it doesn't detect the hard drive upon next boot. If I go into BIOS, no SSD detected. If I pull the battery, hit the power button, put battery back in, it'll run fine for a while.
I'm up in the air if it's a hard drive issue or motherboard issue. Once I got this kernel panic I sat here for a half hour on another system typing it up. I hope somebody can look at it and make sense of it and tell me what essentially is happening.
Im am building a Linux distro. It will be very tiny and fast.
I only have a minimal linuxkernel (bzImage) who is 1,2 mb big. And then I have Busybox who is 174,6 kb big.
The commands in busybox is: cd, ls, mkdir, rmdir, wget, httpd, clear, rm, poweroff, halt, reboot, fdisk, mount, umount, free, and cp.
When I compiled the kernel i use initramfs/initrd function and point it to a folder where initrd/initramfs source is.
The kernel works OK with others initramfs/initrd files. But not with my own.
Quote:
Here is how the end of the kernelcomplie look like.
Quote:
Here is my init file who is the initrd/initramfs source.
Quote:
The initramfs folder contains "bin" (folder) and "init" a file. No more.
The problem is that the kernel cannot find/read init file.
Edit: The PC is broken and I'll buy a new one. Don' bother reading this thread.
I have Kubuntu 9.10 installed on my Acer 7520g laptop. It used to work fine.
But recently my laptop has often went into kernel panic, sometimes at boot, sometimes after hours of normal usage. Today it has not been able to boot properly from HD a single time.
When I boot it up in recovery mode, it kernel panics and displays this (normal mode displays just the graphical progress bar, no text):

I'm sure this is a pure software problem, because Ubuntu 7.10 LiveCD boots up normally and I got X, Gnome and everything working. So CPU must be working perfectly.
I read the logs in /var/log but there were no error messages.
I decided to try Kubuntu (10.4 64bit) again today, it's been a few years since I last tried it. The installation went well, but now I don't seem to be getting past Grub.

My main worry is, obviously, the kernel panic.When booting 64bit machines (a laptop and a desktop), everything works fine, but when booting a 32 bit netbook or thin client, I get the above panic.
I installed mythbuntu from a live CD on an old machine with an IDE hard disk just to play with it. It worked a treat, so I bought an Acer Aspire Revo R3610 and used dd to copy the old HD contents to the new one, and then gparted to resize the ext4 partition.
On boot I got - Kernel panic: VFS: Unable to mount root fs on unknown-block(0,0)
I checked every grub2 command and it all looked fine. I then tried booting the original kernel that the live CD installed (2.6.31-14) and it booted! I tried 2/6/31-17 again, and got the panic.
After much googling, I found a suggestion to do - sudo update-initramfs -k all -c -v and this worked.
Is this expected behaviour? One of the delights of Linux is that installs move smoothly between machines, but this one didn't. Was this due to the old machine using IDE and the new one AHCI SATA? How do I get an initramfs that's flexible and will boot smoothly on any given hardware?
