Hmm, it still fails for my 1542CF..

If I #if 0 out the sending of the buslogic ESETUP command, it works fine 
(except for not doing fast scsi):

[..]

da1s1: type 0xa5, start 0, end = 4124735, size 4124736 : OK
[..]

If I use the unmodified code, and boot with -v, I get this:
aha0: Invalid command 0x4
.. and that's it.  Without -v, silence..


Hmm.. Footnote, I added a second hard reset after the ESETUP command in 
aha_probe() and that also fixed it.  Perhaps we should be hard resetting 
in on a stuck invalid command instead of a soft reset?  - although this 
won't help aha_fetch_adapter_info() which won't retry the GET_BOARD_ID 
command which got lost.

Cheers,
