Hello. I'm struggling a IBM x336 machine with FustionMPT LSI53C1030.
This controller can't do radi0 so I disabled raid in the BIOS.
Problem is that disks are detected wrong and IO is very slow
hdparm -t gives only 37MB/s
dmesg shows that both disks are recognized as FAST-20 while it should be
FAST-160. also cache is disabled.
I've googled around for hours, saw many problems related to the MPT being
slow when compiled into the kernel in old versions (I have tried module) but
I'm using using 2.6.31.
Here are some logs:

I'll appreciate any help.
Thank you.
