CentOS - Sep 2004 - Getting kernel panic when installer starts formatting partitions. Was: How to get 3Ware 9500S controller card working in CentOS 3.1?

In regard of the e-mail sent on Jul/16/04 about the 3Ware 9500S.

 Has anyone experienced/solved this issue ?? I'm having a similar problem, I
already have the system installed on a separate disk, now I want to make the 
filesystem on the RAID partition (using 3Ware 9500S-8). 

 First I had the problem that the card will keep resetting after continous 
timeouts whenever I tried loading the module (compiled from source, in 
up-mode, driver v.9.2 from 3Ware's website). The solution to this was to 
disable APIC on the motherboard (or boot linux without APIC support).

 So, now the module loads ok (I've tried SMP and ENT versions, I'm using
kernel 2.4.21-15.0.4-ELsmp). But the timeout and reset problem start 
happening again when I try to create the filesystem on the RAID partition. I 
can cancel the mkfs operation, but then I get a kernel panic if I try to 
unload the module (rmmod 3w-9xxx), just like the problem that the previous 
poster had.

Any ideas or input would be appreciated.

David

Hi David,
I  definitely solved my problems recompiling the kernel  with 3ware
7006-2 RAID1 driver statically compiled in.

I read this thread :
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121434#c43

and after some problem (EXT3 error) I decided to recompile from
standard sources.

Sure, thanks to Scott suggestion, You can also recompile only the
3ware driver modules and all work fine but the CPU iowait under
some circumstances go up 70/80% and this is unacceptable.
