Public bug reported:
There is about a couple months I experience kernel freezes gets under
some stress, like building a kernel from source (not always though) . I
have reported one of these issues +bug/909103
Quite often the freezes result in different call traces, where I see the
following message
INFO: task Xorg/compiz blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message
The display becomes locked vt1-7. An ssh login is possible though, I try
killing gdm process from there. It does not bring my display back
though. I subsequently reboot. Quite few similar problems of locked
process have been reported before where some people would get their
machines unlocked after a few minutes.
I see it on a number of kernel versions 2.8 and 3.0, both generic and
custom. I suspect have been suspecting the radeon driver and tried to
revert all the commits between versions 3.0.14 and 3.0.17, I still
experience the bug. I was compiling the new 3.0.18 and will be testing
it.
The call trace will attached above.
