Hmm.. that last patch didn't do it. I've noticed some errors on the
console before the lockup:
unexpected md driver lock: 0xe1813900: type VREG, usecount 2, writecount 1, refcount 3871, flags (VOBJBUF)
tag VT_UFS, ino 4, on dev da0s1h (13, 131079) lock type inode: EXCL (count 1) by pid 6
unexpected md driver lock: 0xe1813900: type VREG, usecount 1, writecount 1, refcount 3874, flags (VOBJBUF)
tag VT_UFS, ino 4, on dev da0s1h (13, 131079) lock type inode: EXCL (count 1) by pid 6
This occured both with and without my patch. Perhaps it is responsible
for the problem? My 'cp -pr /boot /mnt' gets stuck in an inode lock
and bufdaemon gets stuck in wdrain.
