I have this same exact motherboard (graciously donated by someone for me
to try to help solve this problem) and the same exact problem.
I don't have any shared interrupts, but the USB subsystem is not getting
any interrupts through to it.
Attached is my kernel startup log with DEBUG enabled in pci.c. This is
for 2.4.0-test12 as I haven't seen any pci changes in the test13-pre
series yet. 2.2.18 also has the same problem.
If anyone needs any other information, or can suggest anything else,
please let me know.
thanks,
