Thanks, these fix the previous panics reported by me.

I was able to produce yet another panic:

mount /mnt/stuff
mount -u -o rw /mnt/stuff
touch /mnt/stuff/foo
mount -u -o ro /mnt/stuff
umount /mnt/stuff

At this point I get this:
g_vfs_done():ad1s1[WRITE(offset=4096, length=4096)]error = 1
g_vfs_done():ad1s1[WRITE(offset=8192, length=4096)]error = 1
g_vfs_done():ad1s1[WRITE(offset=20480, length=4096)]error = 1
g_vfs_done():ad1s1[WRITE(offset=27380416512, length=4096)]error = 1

A few seconds later I get this:
Fatal trap 12: page fault while in kernel mode
current process = 55 (syncer)

trace
g_io_request()
bufwrite()
vop_stdfsync()
sched_sync()
fork_exit()
fork_trampoline()

If I do not use mount -u but simply unmount and mount rw afterwards
there seems to be no problem. (So this is not that critcal for me)
