The scheduler makes very little difference.

Yes, it appears to be mptspi driver (CCing linux-scsi@).
Another problem we've hit while trying various kernels/options
(and which makes whole experiment very dangerous for us) -- after
loading 3.0+ kernel, the machine does not always boot back to
older kernel, often freezing while mptspi is initializing or
starting doing something, so that only hard reset helps. And
since this is a remote production server, the fact that it can
freeze any time we do some experiments makes the whole issue
quite difficult. It appears that 3.0+ driver does something
with the controller which makes at least 2.6.32 kernel/driver
misbehave, at least sometimes.

There's one difference between my 2.6.38 and 3.0 configs --
in 3.0+ I enabled CONFIG_SCSI_SCAN_ASYNC. But due to the
above I'm not sure I want to experiment right now again,
as I need some remote hands to bring the machine back if
it'll stuck again.
And there's at least two quite significant (I think)
differences in dmesg output.

These warnings is what prompted me to try a more
recent kernel actually, plus the fact that 2.6.32
is reaching its end of line (so to say). These
warnings aren't always shown, sometimes it boots
fine.
Here's a dmesg from 2.6.38 kernel, which shows no
issues whatsoever:

The warnings shown in 2.6.32 dmesg above aren't always
shown, sometimes (more often than not) it boots without
any warnings, like this 2.6.38 dmesg.

(Only one port from the two is in use).
Are there any other guesses about all this?
Thank you!
