Re: SCSI QLA not working on latest *-mm SN2

[Paul Jackson <pj@sgi.com>]

Andrew Vasquez has been looking at this, via private email with just
me (no progress yet).  Figured I update the larger list with this much ...

I am still seeing the SN2 SCSI QLA failure as I reported yesterday, but
now against 2.6.9-rc2-mm1.

For the benefit of those with limited memories, such as myself, I will
repeat the symptoms from the top.

Those with good memories can probably stop reading here - nothing much
new to report other than retesting on 2.6.9-rc2-mm1.

===

This is now testing against 2.6.9-rc2-mm1, plus a one line workaround
for some ACPI problem, from Jesse Barnes.  The symptoms resemble what I
first saw of this failure on 2.6.9-rc1-mm5.  I did not see any such
problem on 2.6.9-rc1-mm4.

I have to make the following change to sn2_defconfig in order to boot:

< CONFIG_SCSI_QLA22XX=y
< CONFIG_SCSI_QLA2300=y
< CONFIG_SCSI_QLA2322=y
---
> # CONFIG_SCSI_QLA22XX is not set
> # CONFIG_SCSI_QLA2300 is not set
> # CONFIG_SCSI_QLA2322 is not set

Once I comment out these QLA lines, I can boot.

Otherwise the boot fails, ending with the following lines of output. 
There are a couple of 5 or 10 second pauses somewhere in the last dozen
lines of this output.

By way of comparison, the lines just before and after the above
point of death, on a successful boot w/o the QLA2 config, looks like:
