In this case, the driver does some cleanup, including an mtx_destroy(9). The panic happens because the code tries to use the destroyed mutex. The previous core.txt.6 made me think the code we added for vt(4) didn't check the state correctly. But core.txt.7 shows this happens with a regular ioctl as well. The crash was fixed in Linux 3.10.
