Well, no messages on the console, no ddb (I have vidconsole), no pings, etc. So interrupts aren't getting through, or if they are their threads aren't running, and since I use preemption on this alpha, that is very, very unlikely. I'm assuming it is genuinely deadlocked or possibly spinning somewhere with a raised IPL. > Drew -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
