I remember doing battle with this issue when I switched my frontend to
FC3 from gentoo. Now I have put everything into the master backend
(PVR350, PVR500MCE) and it has appeared again, and obviously rebooting
every time it happens is not an option for a general server/master
backend.
The frontend was an Asus Pundit (SiS chipset) and the server is some
generic Intel mainboard with a P4, so this may not work there, but I think
I "solved" it last time by
1) Disabling the printer port in BIOS, and
2) Adding "parport=0 noapic nolapic acpi=off" to the kernel line in grub.conf.
Can't remember if that was what actually did the trick, will check when I
get home tomorrow... =)
