The reproduction I have is exactly what Rob reported above, except it's on a 386 with a 1542B SCSI controller. [The system is set up with a sio console; and boots off of the floppy - NFS mounting some things... then you can newfs/fsck the hard disk all you want, and do kernel debugging, reboots, etc...] Currently, it's "off the net" - but I can bring it back at the drop of a hat... If anyone is interested in pursuing this; just let me know. - Dave R. - To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
