is there a chance you could use the the mpt-4.x driver? The other simple
way would be to use the driver from the SLES10 kernel (SLES10 without
any service pack, so 2.6.27).
I think you could simply replace the drivers/message/funsion directory.
I definitely cannot recommend to use a more recent kernel, as I know
from Q-Leap that recent kernels run into DV (domain validation) races,
which they 'solved' by introducing simple sleeps into the code.
I'm still in contact with Q-Leap, but decided to take another job some
time ago....
Cheers,
Bernd
