Public bug reported:
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.
