I have found several issues. This is the first one: Jul 13 18:37:43 beastie kernel: lock order reversal: Jul 13 18:37:43 beastie kernel: 1st 0xffffff0007d42ba8 ufs (ufs) @ /usr/src/sys/kern/vfs_mount.c:1199 Jul 13 18:37:43 beastie kernel: 2nd 0xffffff002e007270 devfs (devfs) @ /usr/src/sys/fs/msdosfs/msdosfs_vfsops.c:944 Jul 13 18:37:43 beastie kernel: KDB: stack backtrace: Jul 13 18:37:43 beastie kernel: db_trace_self_wrapper() at db_trace_self_wrapper+0x2a Jul 13 18:37:43 beastie kernel: _witness_debugger() at _witness_debugger+0x2e Jul 13 18:37:43 beastie kernel: witness_checkorder() at witness_checkorder+0x81e Jul 13 18:37:43 beastie kernel: __lockmgr_args() at __lockmgr_args+0xcf3 Jul 13 18:37:43 beastie kernel: vop_stdlock() at vop_stdlock+0x39 Jul 13 18:37:43 beastie kernel: VOP_LOCK1_APV() at VOP_LOCK1_APV+0x9b Jul 13 18:37:43 beastie kernel: _vn_lock() at _vn_lock+0x47 Jul 13 18:37:43 beastie kernel: msdosfs_sync() at msdosfs_sync+0x227 Jul 13 18:37:43 beastie kernel: dounmount() at dounmount+0x2ca Jul 13 18:37:43 beastie kernel: unmount() at unmount+0x28a Jul 13 18:37:43 beastie kernel: syscall() at syscall+0x1af Jul 13 18:37:43 beastie kernel: Xfast_syscall() at Xfast_syscall+0xd0 Jul 13 18:37:43 beastie kernel: --- syscall (22, FreeBSD ELF64, unmount), rip = 0x8006a09ac, rsp = 0x7fffffffdc38, rbp = 0 --- Jul 13 18:37:44 beastie gnome-keyring-daemon[61245]: removing removable location: volume_size_4144496640 I got this while trying to unmount a USB device. The unmounting seemed to be fine, all the files were in the device and no corruption occurred. I found a very similar problem (maybe the same) here[1]. Any clues about this? Thanks in advance.
