The problem seems to be in incorrect interaction between devfs_close_f and linux_file_dtor. The latter expects curthread->td_fpop to have a valid reasonable value. But the former sets curthread->td_fpop to fp only around vnops.fo_close() call and then restores it back to some (what?) previous value before calling devfs_fpdrop->devfs_destroy_cdevpriv. In this case the previous value is NULL. -- Andriy Gapon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
