This is a known problem (assuming that you got a panic: lockmgr: locking against myself). The mount system call has an exclusive lock on '/' while ffs_mount tries to perform a lookup on '/dev/rfd0'. PR kern/434, kern/1031, kern/1067, kern/2174 reports the same problem. I've sent a suggested fix for PR#1067. - Tor Egge To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
