Thing is, I don't know much about DDB:
kernel: page fault trap, code=0
Stopped in pid 3(cardslot0) at pcmcia_scan_cis+0x25a: movb 0(%edx,%ex,1),%dl
pcmcia_scan_cis(c0b0a200,c03a9d9c,cb31aec8) at pcmcia_scan_cis+0x25a
pcmcia_read_cis(c0b0a200) at pcmcia_read_cis+0xcd
pcmcia_card_attach(c0b0a200) at pmcia_card_attach+0x39
cardslot_event_thread(c0b14280) at cardslot_event_thread+0x364
Now what? BTW I compiled it with PCMCIACISDEBUG & DIAGNOSTIC/DEBUG and
nothing is printed before the panic..
