I've played with the settings Ted suggested, and here's what I found:
Case 1: hw.pcic.intr_path=2 and hw.pcic.init_routing=1
Result:
Unchanged (card probes twice, followed by hang)
Case 2: hw.pcic.intr_path=1 and hw.pcic.init_routing=1
Result: Hangs as soon as the card is inserted
Case 3: hw.pcic.intr_path=1 and hw.pcic.init_routing=0
Result: Hangs as soon as the card is inserted
Any ideas?
Thanks,
Lars
