That is fairly interesting, but may be a red herring. The code that prints that out basically just runs killall5 -9 with any pids still running as arguments. After that it will exit, so I suspect the problem is further down. There are quite a few scripts between sendsigs and halt.. lrwxrwxrwx 1 root root 18 2010-10-22 13:47 S20sendsigs -> ../init.d/sendsigs lrwxrwxrwx 1 root root 17 2010-10-22 13:47 S30urandom -> ../init.d/urandom lrwxrwxrwx 1 root root 22 2010-10-22 13:47 S31umountnfs.sh -> ../init.d/umountnfs.sh lrwxrwxrwx 1 root root 20 2011-07-14 13:34 S35networking -> ../init.d/networking lrwxrwxrwx 1 root root 18 2010-10-22 13:47 S40umountfs -> ../init.d/umountfs lrwxrwxrwx 1 root root 20 2011-07-21 13:55 S48cryptdisks -> ../init.d/cryptdisks lrwxrwxrwx 1 root root 26 2011-07-21 13:55 S59cryptdisks-early -> ../init.d/cryptdisks-early lrwxrwxrwx 1 root root 20 2010-10-22 13:47 S60umountroot -> ../init.d/umountroot lrwxrwxrwx 1 root root 14 2010-10-22 13:47 S90halt -> ../init.d/halt Would be helpful to mod them all with 'set -x' so we can see what the last command is before the system fails to shut down. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde-workspace in Ubuntu. https://bugs.launchpad.net/bugs/859075 Title: Oneiric does not shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/upstart/+bug/859075/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
