Since the release of the May 15 NetBSD-current i386 snapshot, there
have been several reports on this list about the GENERIC kernel failing
to boot due to the probes mistaking an Adaptec SCSI host adapter for a
BusLogic or vice versa.
I'll join the flood with my own observations: the boot floppy failed
on two out of two machines I tried. One has an Adaptec 1542A and the
other has a 1542B. In both cases the bt0 probe succeeded although
neither machine has a BusLogic card, and the kernel then either
hung or panicked in the bt0 driver.
Here is a manual transcription of some of the messages seen on the
console of the machine with the 1542A.
bt0 at isa0 port 0x330-0x333 irq 11 drq 5bt0: bt_cmd,
cmd/data port full
:version 0.6, bt-127428592: bt_cmd, cmd/data port empty 7
