We have been having the same problems and have exact steps to get it 
working.  We have the same model perc card and now have 1 of our 4 
servers running CAS 4.1.2.

Step 1 - you need to go into the RAID bios, remove the current VD. 
Recreate it as Raid 1 and do a FULL init and NOT a QUICK init.
Step 2 - in 1950 bios you need to have serial ON without redirection and 
the redirect after boot set to disabled.

Other than that all bios setting should be default.  After you do your 
install with those changes your server should run fine without the 
kernel panic.

Just as a side note we also changed our nic setting in the bios to 
enabled WITHOUT PXE just to speed up the boot process but that would be 
totally up to you.
