kernel BUG at /build/buildd/linux-3.5.0/fs/buffer.c:3199!; RIP: 0010:[<ffffffff811b33d6>] [<ffffffff811b33d6>] free_buffer_head+0x46/0x50

[Gerben]

Hi,

A kernel bug was shown to me on the monitor, the system continued running.
The problem was shown in a process running a KVM client, the client started resetting a device (windows client: 129: Reset to device, \Device\RaidPort1, was issued.)

From the syslog I could extract the kernel BUG message:

This change was made by a bot.

[Gerben (gerbgeus)]

The whole libvirt installation stopped to be responsive when trying to shutdown client (reboot in client, and after that "force shutdwown" withing virt-manager)

Both virt-manager and virsh list stopped to display results.

Two more "kernel BUG" messages could be found from syslog (one more file attached containing two messages)

A reboot on the host was issued, a second reboot after a few minutes made the system perform the reboot. After that everything look OK.

[Joseph Salisbury (jsalisbury)]

Do you have a way to reproduce the bug, or was it a one time event?

[Gerben (gerbgeus)]

No way to reproduce the bug. The kvm client was moving a lot of data (22GB newsreading, unpacking).

The kvm host was a clean 12.10 64-bit server install, all updates performed

I'm having more problems running 12.10, (see Bug 1158995) and frozen system which I've not reported

The frozen system reported the following issues:
  - file system got remounted ro
  - logging on to the system I was told to check filesystems (referring to /etc/mtab)
  - command 'df -h' did not complete, presenting me a 'Bus error'

(one more file attached)

Gerben, as per http://www.asus.com/Motherboards/SABERTOOTH_990FX/#support an update is available for your BIOS (1604). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.
