I have a bug (36242 at the unavailable kernel bugzilla and 684424 in Fedora)
where sound being played using my motherboard sound chip and high I/O
(it seems like network traffic more so than disk) results in a hang.
I haven't been able to get a crash dump or traceback once the hang occurs. I'd
be interested in getting this bug looked at, but I think I need some
suggestions for how to get a traceback, or there isn't going to be enough info
to track this down. I tried some kernel boot parameters to get watchdog
timeouts, but that didn't work. Maybe I need to rebuild the kernel with
a different config to really enable that feature though?
The kernel-debug rpm should have everything you'd need.
Hardware specific problems like this are a nightmare for us to diagnose.
It might even come down to you needing to do a bisect to find the individual
kernel change that caused the problem. (assuming you know a 'good' version
to start from)
