This is probably the problem with my AS4100 -- it hangs in probing the SCSI chain -- just like the PC164's did. My guess is there is something in your 4100 that helps get off an interrupt at a key moment. Does anybody know if DFR's 4100 can run -current? -- -- David (obrien@FreeBSD.org) GNU is Not Unix / Linux Is Not UniX To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
