Interesting. I'm not able to get anything to use int 5, and you have
eth0 there, which is what I would really like to try. I just tried
turning on PNP and clearing the config in the BIOS, and trying ACPI.
From the boot log, it looks like it will only route to interrupts 10,
11, and 15. Maybe I'll hop over the the viaarena forum, and see if they
have any ideas.
I notice you have yenta loaded, google tells me that's pcmcia related.
Are you using an MII? Is your eth0 on pcmcia, or are you using built
Also, you have ivtv loaded, not too many ethernet interrupts, and quite
a few ide0 interrupts. Is your system just a frontend, or is it both
frontend and backend? I ask because when the nuv files are local, I
don't see the problem.

With XvMC and .18 on the frontend only Epia, I am seeing roughly 20%
cpu usage, which makes this problem even stranger. About 3% cpu on
hardware interrupts, 3% on software interrupts, and 0% wait. That's
what's making me think network latency now, and checking out the shared
video/ethernet interrupts situation.
Now that I have a disk in there, and no longer need net boot, I'm going
to try a nic in the pci, and see if I can get it on a different
interrupt that way, just for giggles.
Thanks for the info.
