Description of problem:
I have experienced several system freezes during the last days, most
occur when the system is under interrupt load somehow. Today I managed
to grab a panic while using transcode capturing a live tv feed (bttv
driver) into a file on disk:

I will try to get the same for the latest rawhide kernel.

Version-Release number of selected component (if applicable):
kernel-2.6.10-1.1063_FC4

How reproducible:
Sometimes

Steps to Reproduce:
1. Unknown. IO/Interrupt load seems to help.
2.
3.
    

Actual Results:  system freeze

Expected Results:  normal operation
