Disabling IRQ

After about half an hour of watching a video, I get this message.
(Xine dies immediately and mplayer continues on for a few minutes
more, then eventually dies, as well). It only happens when watching a
DVD directly or ripped using either perfect or compressed.

mythtv kernel: Disabling IRQ #185

It's disabling my sound card that I'm not using (on board sound is
enabled, but I'm using my SoundBlaster Live card for everything) and
for some reason my USB ports to which I have attached a wireless
Microsoft USB mouse. Mouse still works after these messages, just
REAL slow/choppy movement. Anyone have any idea why? And why only
when watching a DVD? Any other info that would be useful in
diagnosing? Even advice as to which list I should be posting it to
would help. :)

I had this happen on my server.
Problem I had was related to RAID-5 controllers which were disabled
after heavy activity.
I'm running a MSI 694D board with two PIII-800 processors.

The fix was to force the IRQ selection off from Fedora with a Grub boot
command.
Don't know if it helps but this what is working for me.
"pci=noacpi"
This is placed to the grub.conf after the kernel string

As far as I recall, I've got the same motherboard (I have 3 dual
processor boards and I never remember which is in which box). I added
the kernel switch and now I'm playing through a movie now to see if
it solved the issue. Thanks!

At least my IRQ's look reasonably assigned now.
