Bug Description

After the most recent kernel upgrade to 12.04 released on or about November 8th 2013 my machine started to freeze after a variable period of use but only a few minutes in each case. The only thing I could then do was to power down and reboot - file system errors were usually found on restart. fsck was able to fix those. I have never previously had any such problems.

Two full passes with Memcheck found no errors and disk utility reports no disk errors - read error rate is 0, reallocated sector count is 0.

I have enabled the Grub menu and am now using 3.2.0-54 with no problems at all.

The kernel and system logs do appear to show call stack dumps and 'BUG' messages.

Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.2 stable kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I have not been able to test the upstream kernel - it seems to be unable to set my graphics card to produce any output.

However, I have been able to create a fresh install of 12.04 on a different hard disk - the other hardware exactly the same, just a different hard disk. I started with the original 12.04 CD and then took all the available updates including 3.2.0-56 so that the setup should have been as near as possible the same as the one that caused trouble.

The result is - it seems to run just fine. Hence at the moment my assumption is that the problem was due to some unidentified mishap during the update to 3.2.0-56.

I am intending to do an install of 13.10 to a different hard disk. When I have that established as a working environment I will try a surface scan of the disk with the problem setup and perhaps try to uninstall and reinstall 3.2.0-56 to see what happens.

I do have a copy of the relevant kernel log showing call stack dumps and 'BUG' messages that I could add if you think it would be of any help. Otherwise I will update this report if I can find anything that might be of interest when I am in a position to investigate further.

Having put some effort into testing I am unable to make the problem recur.
I have to conclude that I had some transient hardware problem with this machine that just happened to occur a few hours after the upgrade to 3.2.0-56 was made. As of the next day nothing like it has happened again.
I have reseated the ram cards as a precautionary measure.
