aha1542.c: interrupt received, but no mail.

If this error occurs rarely there is no problem, as it's just reporting on what
happens. I removed a similar warning from the obsolete BusLogic driver before
rewriting it entirely.

BusLogic SCSI: buslogic_out: failed(4) Buslogic SCSI: buslogic_stat status=39 intrflags 84
BusLogic SCSI: setup_mailboxes: failed setting up mailboxes.
aha1542_in failed(3): Unable to determine Adaptec DMA priority. Disabling board
No BIOS32 extensions presnet. This release depends on it. Sorry.
scsi : 0 hosts.

This is due to problems with the obsolete BusLogic driver as described in the

6. Linux 1.2.x gives the message

Unable to determine Adaptec DMA priority. Disabling board.

This is due to a conflict on some systems with the obsolete BusLogic
driver. Either rebuild your kernel without it, or give the
BusLogic driver a command line option telling it to look
somewhere other than where your controller is configured. Ie,
if you have an Adaptec board at port 0x334, and nothing at
0x330, use a command line option like


So, you can keep the obsolete BusLogic driver from interfering with the Adaptec
1542 driver for your hardware by using the command line "buslogic=0x130".
