Description kevinmills 1999-11-06 05:46:01 UTC

During the install, my Adaptec 2940UW was detected and my
hard drive was found as /dev/sda.  My CDROM and Jaz drive
are on an Adaptec 1542 and, after choosing that driver, the
Jaz was detected as /dev/sdb.  Installation proceeded
normally.  However, upon re-boot the Adaptec 1542 driver
was loaded first causing my Jaz to be /dev/sda.  The
aic7xxx driver loaded next and made my hard
drive /dev/sdb.  This caused a kernel panic - no root fs.

My /etc/conf.modules file *does* list them in the correct
order; the aic7xxx driver is first and labled
scsi_hostadapter and the 1542 driver is second and labled
scsi_hostadapter1.  However, they do not load in this order.

I am forwarding this to a developer for further action, but in the
mean time, you can try the following and see if it helps you out.

In conf.modules, on the aic7xxx line, add "aic7xxx reverse_scan"
which should force recognition in the reverse order.

More info:

adding the reverse_scan line did *not* change the behavior.

I had the same problem with two SCSI adapters. I fixed it by changing
scsi_hostadapter to scsi_hostadapter0 for the adapter that the hard drive is on
(and leaving scsi_hostadapter1 for the adapter that my SCSI zip drive is on.  It
appears that the one for the second card is ignored unless you have a zero for
the first card

Comment 7 kevinmills 2000-02-10 17:17:59 UTC

I tried adding a '0' to scsi_hostadapter and saw no difference.  It behaved
exactly the same no matter which card was scsi_hostadapter0 or 1.

Comment 8 Jay Turner 2000-02-22 15:07:59 UTC

This issue is resolved in the latest cut of the installer (available in beta)
