   Going from 8th march kernel to 25th march kernel made the system very
   unstable (three crashes last night).  These seem to be load related.  NFS
   or SCSI are the primary suspects.  March 8th kernel was reliable.

   None of the crashes produced a dump.

One more crash:

sd3(ahc0:3;0): SCB 0x6 - timed out in command phase, SCSISIGI == 0x86
SEQADDR == 0x12c
sd0(ahc0:0:0): abort message in message buffer
sd1(ahc0:1:0): SCB 0x1 timedout while recovery in progress
sd3(ahc0:3:0): SCB 0x3 ...
sd1(ahc0:1:0): SCB 0x7 ...
sd0(ahc0:0:0): SCB 0x0 - timed out in command phase, SCSISIGI == 0x96
SEQADDR = 0x8f
sd0(ahc0:0:0): no longer in timeout

[deadlock]

Is there ongoing instability with ahc driver and 3940 ?
