SCSI QLA not working on latest *-mm SN2

[Paul Jackson <pj@sgi.com>]

Andrew Vasquez,

[My inbox had a message recommending a copy linux-scsi as well,
 so resending to include that list as well. ]

Jeremy Higdon recommended I send this to you.  I am running into
a fatal problem with SCSI QLA2, unable to boot using the latest *-mm
on SGI's SN2 hardware (don't know if other hardware involved or not).

This is on 2.6.9-rc1-mm5, and more recent variants of *-mm.

$ grep QLA2XXX_VERSION drivers/scsi/qla2xxx/qla_version.h
#define QLA2XXX_VERSION      "8.00.00b21-k"

My source currently includes the patch of Monday that begins:

I am pretty sure that I also saw this problem earlier Monday morning,
before this patch.

Beginning with 2.6.9-rc1-mm5, I have had to comment out some of the QLA
config options in order to boot on an SN2.  That is, unless I make the
following edit to my .config:

my boot fails with the following output:

========================================

This is on a couple of small (4 and 8 cpu) SN2 systems, that boot with
earlier kernels just fine.
