Suspend fails with a kernel BUG in dvb driver

Description of problem:
Suspend fails with a kernel BUG apparently related to dvb:
kernel BUG at drivers/media/video/video-buf-dvb.c:58!
Sep 29 04:24:23 localhost kernel: invalid opcode: 0000 [#1]
Sep 29 04:24:23 localhost kernel: SMP
Suspend hasn't worked for me for sometime, but I am just now looking into it.
It may have to do with my installation of mythtv (suspend did work some time ago
on my machine, but before mythtv).
Version-Release number of selected component (if applicable):
Using kernel.i686 126.96.36.199-49.fc6
Also suspend didn't work with earlier recent kernels, but I don't have any
details of the failures to be sure they are the same.
Every time I try to suspend.
Steps to Reproduce:
1. Try to suspend on a computer with a similar configuration.
Suspend fails, computer half asleep, monitor off, disks and CPU apparently
running, won't wake up
Suspend, or if not suspend, resume

An excerpt from /var/log/messages including stack, and installed package configuration
Note on reproducibility: get the same Behavior every time I try to suspend, but
not the kernel BUG. (Sorry, I didn't realize this at first).
Another Note: If I remove the USB lirc port, so that lirc_dev doesn't load, my
machine suspends and resumes normally.
So, perhaps the only useful part of the bug report from the kernel point of view
is that when a thread (in this case lirc_dev) refuses to freeze, the attempt to
restart all the tasks does not bring the machine fully back to resume. I have
to do a hard powerdown. Of course, the simple way to avoid this is to avoid
suspend when lirc_dev is loaded.

I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.
I am CC'ing myself to this bug, however this version of Fedora is no longer
Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.
Thanks for using Fedora!
