Ok, short answer is you have a busted MP Table as it is incomplete. You can try disabling USB as a hack for one to test if that fixes your problem. I would be interested in seeing your mptable output. > pcib0: unable to route slot 7 INTD > found-> vendor=0x8086, dev=0x7112, revid=0x01 > bus=0, slot=7, func=2 > class=0c-03-00, hdrtype=0x00, mfdev=0 > cmdreg=0x0005, statreg=0x0280, cachelnsz=0 (dwords) > lattimer=0x40 (1920 ns), mingnt=0x00 (0 ns), maxlat=0x00 (0 ns) > intpin=d, irq=11 > map[90]: type 4, range 32, base 00005000, size 4, enabled This is your USB controller and is what has the problem FWIW. Note the message from pcib0 about being unable to route an interrupt. Let me know if just disabling USB is enough to fix the problem for now. If it is we can go from there. -- John Baldwin <jhb_at_FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.orgReceived on Fri Feb 04 2005 - 21:12:43 UTC
