Re: Buffer underrun errors
Before you start rearranging your cards, it's easier if you could first post the output of the following commands:
# lspci -vv
# cat /proc/interrupts
Then, if you are using ACPI you could try to reboot with the option "acpi=nopci", or, if that doesn't make the problem go away, "acpi=off". If you are running grub, you have to press
'e' to edit the line displaying the kernel you are about to boot (simply append the option to the given line), else if you are using LILO press shift after power up so you get a "boot:" prompt and type "linux acpi=nopci" or "linux acpi=off" (assuming you have called your boot image "linux" which is the default I think).
