As Werner from SuSE said before, pre-10 + AIC7xxx is only safe, iff you
don't enable one of the extended features. I had this reproducable:
scsi0: References SCB 255 not valid during SELTO
SCSISEQ = 0x5a SEQADDR = 0x4 SSTAT0 = 0x15 SSTAT1 = 0x8a
and then a lot of 'aborting command due to timeout' and SCSI resets.
