RE: kernel: aacraid: Host adapter reset request. SCSI hang ?

Because I have the same problem ( see my post earlier
), I don't understand where you disable this
hperthreading functionality ( maybe it is only for PIV
or a DELL server). I have a bi-processor Athlon MP,
can I do the same and finally, is that sure our
problem comes with this.

Thanks ...
