Hi everyone,
	My SCSI problems have generated some new errors, which might be
helpful in diagnosing the problem. The system is a dual PIII (Tyan
S1368) w/1Gig PC133, adaptec 2940UW and Arena Raid array. 
Would enabling kernel cores help? Is there anyone that can diagnose those
who isn't already too busy?
The first error is the one I've already seen, all the rest are new:

Sep 12 11:08:20 thermal /kernel: ahc0: ahc_intr - referenced scb not valid
durin

then the system crashes.
