I was thinking of panic'ing the system at that point in case it happens again to get a crash dump, but i have a problem in that this is an ISA machine with an ah1542, so i would only get the first 16Mb of a dump (i think) :-( I think maybe we need some bounce buffer hacks in the scsi dump code... either that or buy a decent board :-) Cheers, Karl -- ------------------------------------------+----------------------------------- Mailed using ELM on FreeBSD | Karl Strickland PGP 2.3a Public Key Available. | Internet: karl@bagpuss.demon.co.uk |
