Ok; this is different from the "linked" dmesg you were showing before,
and what it's highlighting is the weakness in the algorithm that we use
for picking an interrupt in the "I have no idea what is good" case.
Try taking the "life is tough" loop in sys/i386/pci/pci_cfgreg.c
:pci_cfgintr_virgin() and change it so that it just loops from 11 to 11,
ie.
for (i = 11; i < 12; i++) {
...
I still haven't worked out a "good" way of dealing with this problem; the
way we hand out device resources makes it difficult to know in advance
which interrupts are good choices. 8(

people to take different points of view. [Dr. Fritz Todt]
