Public bug reported:
Binary package hint: linux-image-2.6.24-19-generic
I've got a stuck totem process which is unkillable, apparently spinning
in do_exit(). I just hit "q" to exit in the normal manner, and it's
stuck, using 100% of CPU. The machine still responds to userspace
(hence this bug report).
The only thing particularly interesting here is that totem was playing a
movie over NFS.
This is a Compal CL56 laptop with a Pentium M processor (single core, no
SMP). The only other thing of note is that totem seems to crash on exit
most of the time in pulseaudio, in the pthreads code. Could this have
to do with page faults in multithreaded apps during shutdown or
something?
I suspect I will be unable to reproduce this, but in the hope that it's
useful, here are the stacks I gathered using sysrq:
