Yes, debug_level is not there.

Intel in its site about the mb has an apparently ancient driver 
http://downloadmirror.intel.com/13241/ENG/LinuxMPT_Rel_Notes_3.02.83.20-1.txt. 
I tried the sysctl -ww dev.scsi.logging_level="0x1000" as they suggest and 
it seems to produce tones of irrelevant output. Disabled it.

I am downloading 
http://www.lsi.com/DistributionSystem/AssetDocument/support/downloads/hbas/sas/software_drivers/linux/MPTLINUX_RHEL4_SLES9_PH14-3.13.04.00-2.zip
at the moment and will give it a try.

Cheers,
