Is this by any chance the same stack frame you see when it hangs (or
is yours hung so badly you can't break into ddb and get a stack
trace?).

        gettick()
        delay()         
        __wdcwait_reset()
        wdcprobe()      
        wdcattach()     
        wdc_pcmcia_attach()
        config_attach()
        config_found_sm()               
        pcmcia_card_attach()
        cardslot_event_thread()
        Bad Fram pointer: (hmmm...)
