I was attempting to reinstall it after an abortive previous install. We should see if this is reproducible when installing on a machine that has already been partially (or wholly) installed. Here's the debugging info I got: {{{ debathena / personal / geofft 17:23 (Geoffrey Thomas) .... ... .. why is `lvremove -f /dev/athena/keep_2` hanging in sys_semtimedop? debathena / personal / geofft 17:24 (Geoffrey Thomas) with no other threads? debathena / personal / geofft 17:57 (Geoffrey Thomas) According to gdb, we're in semop in dm_udev_wait in ?? in lv_deactivate in ?? in ?? in lock_vol in lv_remove_single debathena / personal / geofft 18:12 (Geoffrey Thomas) Also at about the same time I got udevd-work[18528]: inotify_add_watch(6, /dev/dm-2, 10) failed: No such file or directory debathena / personal / geofft 18:12 (Geoffrey Thomas) And strace says semop(0, {{0, 0, 0}}, 1 }}} If we can't reproduce this and don't see this again, this ticket should be closed.",task,closed,normal,Natty Release,--,fixed,,,,
