How is it "clearly a SOFTUPDATES problem"? What's clear is that you have something spinning in an interrupt handler. Soft updates may be triggering this, but there's no guarantee that it's the cause of the problem. Start off by making sure that your softupdates files are symlinks to the real thing, not stale copies. Then add DDB to your kernel config, and when the system wedges, hit alt-ctrl-escape, then type "trace" to get a traceback. If you can do this with a debug kernel (config -g ...) that would be even better. -- \\ 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-current" in the body of the message
