As soon as smb_iod_main() does the wakeup() just before the patch (line#623), smb_iod_destroy() can go ahead and destroy the mtuexes. I think the above patch failed because the smb_iod_sendall(iod) and smb_iod_recvall(iod) need to be done before smb_iod_main() returns. I'll email a patch for testing later to-day (I've gotta run and do something else now), rick> > here is what I got on the kvm console: > > login: panic: Assertion mtx_unowned(m) failed at > /usr/src/sys/kern/kern_mutex.c:955^M > cpuid = 1^M > KDB: stack backtrace:^M > #0 0xffffffff80975bb0 at kdb_backtrace+0x60^M > #1 0xffffffff8093baa6 at vpanic+0x126^M > #2 0xffffffff8093b979 at kassert_panic+0x139^M > #3 0xffffffff80921c47 at _mtx_destroy+0x77^M > #4 0xffffffff81a1c114 at smb_iod_destroy+0xc4^M > #5 0xffffffff81a12eea at smb_vc_free+0x1a^M > #6 0xffffffff81a13e24 at sdp_trydestroy+0xb4^M > #7 0xffffffff81a1cb36 at smbfs_unmount+0xd6^M > #8 0xffffffff809d9e84 at dounmount+0x524^M > #9 0xffffffff809d9936 at sys_unmount+0x3c6^M > #10 0xffffffff80d42235 at amd64_syscall+0x265^M > #11 0xffffffff80d25cfb at Xfast_syscall+0xfb^M > Uptime: 19h48m28s^M > Dumping 179 out of 999 > MB:..9%..18%..27%..36%..45%..54%..63%..72%..81%..98%^M > Dump complete^M > Automatic reboot in 15 seconds - press a key on the console to abort^M > > heres the crashinfo: > > panic: Assertion mtx_unowned(m) failed at > /usr/src/sys/kern/kern_mutex.c:955 > > GNU gdb 6.1.1 [FreeBSD] > Copyright 2004 Free Software Foundation, Inc. > GDB is free software, covered by the GNU General Public License, and you > are > welcome to change it and/or distribute copies of it under certain > conditions. > Type "show copying" to see the conditions. > There is absolutely no warranty for GDB.

Hi again, Attached is a semantically equivalent patch to the one I posted a few minutes ago, but I think this one is more readable.
