--dDRMvlgZJXvWKvBx Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi, My system: Current, cvsup'd Mon Mar 25 17:21:05 CET 2003 I load linux-compatability through /etc/rc.conf (linux_enable="YES"). If I unload it (kldunload linux.ko) and then run another command (so far, I've tested kldstat(8) and ls(1)), I get a panic: panic: blockable sleep lock (sleep mutex) Giant @ /usr/src/sys/vm/vm_fault.c:206 The first time this happened was with a system built from yesterday's (March 24) sources. Unloading linux.ko, and running kldstat produced the panic. I noticed that /usr/src/sys/vm/vm_fault.c had been touched since my buildworld/installworld ($FreeBSD: src/sys/vm/vm_fault.c,v 1.164 2003/03/25 00:07:05 jake Exp $) so I cvsup'd and built/installed world again. This time I tested with "kldunload linux.ko" followed by "ls". Panic again. I'll be happy to supply more info if needed (but I'll probably need instructions). You'll find my kernel-config at: URL:<http://www.krutov.org/martink/kernel-config>; While searching on this, I came across a report of a similar crash, to the -current list: (I don't know if this helps) Message-ID: <20030104163145.GT311@goddamnbastard.org> URL:<http://docs.freebsd.org/cgi/getmsg.cgi?fetch=1988511+0+archive/2003/freebsd-current/20030105.freebsd-current>; Attached is a backtrace (at least I think it's a backtrace).
