Good day.
Did anyone succeed to make linux IPS driver work for IBM Ultra3 4-channel RAID
adapter? I've got one of these in my 7025-F50 and it works fine in AIX 5.3, but
when I boot Red Hat FC5-ppc, driver load fails. When booting from rescue or
install CD, I have got a long delay when loading ips.ko, and then kernel bug
message displayed, something like this:

When I boot installed FC5 system (with all updates applied via 'yum'), kernel
does not attempt to load IPS driver. When modprob-ing by hand, it complains
about inability to allocate 256 bytes of IO memory. Quite a pity, as I've got
two sixpacks loaded with disks connected to this controller. The controller
itself is seen from Linux 'lspci' output as 'IBM ServeRAID adapter [4H]', and
from AIX as:

Displayable Message.........UL3RAID

Again, under AIX this adapter looks OK, I am able to create arrays, volume
groups, filesystems etc, nothing reported by 'errpt' command concerning this
card.
I have googled through but did not find any relevant information. Tried to
remove one Ultra3 SCSI adapter from the system (which has boot disks on it), as
we had similar trouble on IBM intel-based xServer 330 machine with ServeRAID 4L,
where RedHat FC4 did not initialize RAID adapter until we disabled onboard
Adaptec controllers. Nothing helped so far.
