I contacted Jeremy off the list about this issue a few days ago. I have one spare box i386 sitting here that I can happily test patches against; if I can be of help, let me know. > uname -a FreeBSD localhost.localdomain 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #0: Tue Nov 11 21:40:27 CST 2008 user@localhost.localdomain:/usr/obj/usr/src/sys/GENERIC i386 > ident /boot/kernel/kernel | grep sleepqueue $FreeBSD: src/sys/kern/subr_sleepqueue.c,v 1.39.2.5 2008/09/16 20:01:57 jhb Exp $ Suffers from the description given by Jeremy: the box is not deadlocked during snapshot but I might as well walk away from it because I can't use it. I'd really like to see this get fixed; I rely on dump for backups. Regards, Pat -- "Jesus, can't I count on you people!?" --Oh Brother, Where Art Thou, George Clooney
