Subject: [RHEL5.0 PATCH]: BZ#205653: cpqarray module fails to detect arrays

RHEL5.0 would not install on the Compaq ProLiant 8500R computers in
the Westford lab (xeon1 and xeon2) because it could not detect the
storage on the built-in cpqarray RAID systems.  This is a regression
from RHEL4.5.  Eventually, I tracked down the problem to the device
not being configured as a PCI bus master.  I have confirmed that this
patch fixes the problem, and that reversing the operation reproduces
the problem.

I have no idea why this patch isn't needed on RHEL4.

I will submit this upstream through HP.
