Ok I have build some Natty kernels with that DEBUG patch applied (note
this is not a fix mearly a mechanism to confirm the root cause). Could
those of you affected please test out these kernels (they should work on
Maverick too) and report back here. The kernels are at the URL below:

From the upstream bug report, they suggest testing with the following
kernel patch:
This patch would confirm my hypothesis that is an invalid unfenced
alignment:

Given the kernel patch from upstream, that seems to indicate this is
going to require fixing on the kernel side. I've notified the kernel
team and will close out the X task at this time.
If for some reason it turns out this does need a patch on the X side,
please reopen the

My comment on that bug:
Hmm, from the dmesg output it sounds sort of like your system was already
'sick' before X hung. Perhaps an out-of-memory situation?
Could you please explain more about the conditions leading to this
system freeze? And have you seen it more often than just this one time?

From the dmesg of one of the dupes:

Hmm, would be curious if the audio player causes an out of memory
situation that crashes X.
Are you able to reproduce this with a specific set of steps? If so
could you enumerate them here? If the issue is caused by the audio
player, then that might help narrow down what it is doing to cause
