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.
