Re: New panic in wdc_ata_bio_intr

I tried the same kernel on a VirtualBox guest - it doesn't crash, but one gets endless 

piixide0:1:0: lost interrupt
        type: atapi tc_bcount: 0 tc_skip: 0

stream of messages. Also /etc/rc.d/swap2 start hangs while trying to add /dev/cd0a as a dump device... as shown by ktruss.

Couldn't get a crash dump.
