Re: ahc driver now borked in -current?

Jordan,

Having the dump card state message will be really useful.  You might
want to examine the message and see if mentions anything about
interrupts not working, or 'SCB already completed'.

BTW, sending problem reports like this to freebsd-scsi_at_ or directly to
myself of Justin will improve your chances of getting noticed =-)
