I have been wondering about HPT37x in Fedora Core (development) kernel
called  kernel-smp-2.6.7-1.501.i686.  It doesn't find one of the cards
attached to a HPT372A card that I have.

I tried also to boot with a bit older kernels: 2.6.3, 2.6.5 do work just 
fine (except of 2.6.5 barfs the keyboard..). 

I tried also with 2.6.7-1.494smp (FC devel kernels), and that too
does fail.  I think I had also some a bit older 2.6.7, also that
one failed.   I didn't get around to try any 2.6.6 kernels.

Any ideas ?  Will this patch help ?
