   >Number:         3162
   >Category:       kern
   >Synopsis:       2.2 kernel from mar 25th crashes on nfs server
   >Environment:

   NFS server with 3940, 64M, 1*1.7G micropolis + 3*4G seagate hawk.  No
   tagged queueing or memory io used (no AHC options).

   >Description:

   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.

Now we managed to copy the panic messages from the console:

ahc0:A:4: not active SCB for reconnecting target - issuing ABORT SAVED_TCL == 0x40
ahc:A:4 Target did not send an IDENTIFY message. LASTPHASE = 0x40, SAVED_TCL = 0x40

   >How-To-Repeat:

   It seems that I managed to get two crashes by saving a 22M file from emacs.
   Emacs probably does one 22M write(2) to accomplish this.
