Did you happen to write down the details from this message? In conjunction with your kernel image, these are required in order to determine what happened. It's possible that something doesn't like being asked to boot from a zero-sized disk. It's also possible that something else later got upset - it's not clear where in the chain of events the panic occurred (see above). Thanks for the extra info. Are you able to simulate the failure by eg. disconnecting one of the 'active' drives? If you can't do this on a regular basis, I believe we are able to arrange temporary access to a similar but idle system where this can be simulate. Simon may also be able to offer some suggestions inre. possible poor interaction between the dpt driver and some firmware revisions. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
