OK, so my understanding is that you start pnmixer, and it starts fine,
then you hibernate, and then you reboot to resume from hibernation,
and THAT is when the crash occurs.
Is this basically correct?

If so, how can we deduce that the system crash is being caused by pnmixer?

You  need to boot a kernel that enables the saving of the system crashdump
and upload it to the redhat's  bugzilla.redhat.com so that the cause of 
the system
crash can be identified.
