           Summary: Breezy sometimes does not manage to reboot
           Product: Ubuntu
           Version: unspecified
          Platform: i386
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: linux
        AssignedTo: ben.collins at ubuntu.com

Hi,

Sometimes, esp. when using "reboot" from the login screen, the last messages on
the console are
* Shutting down LVM Volume Groups
* Rebooting
[4294825.547000] Restarting system
After which the system does not react anymore. I need to power off and on.

The last line ([429...] which looks like Breezy's new style syslog format) seems
suspicious to me, since it does *not* appear when the system manages to reboot
by itself.
I'm surprised to see a syslog-style message. I would have expected syslog etc.
to be long stopped when that state is reached.

The machine is a Fujitsu/Siemens laptop Lifebook C1110.
I can't remember having experience this with Hoary or Warty.

Actually, I wonder whether sometimes kernel logging gets confused: I see
incomplete snippets of lines like in:
Nov  9 13:43:31 localhost kernel: No module symbols loaded - kernel modules not
enabled.
Nov  9 13:43:31 localhost kernel: .617000] Checking if this processor honours
the WP bit even in supervisor mode... Ok.
                                  ^^^^^^^^
Nov  9 17:08:51 localhost kernel: No module symbols loaded - kernel modules not
enabled.
Nov  9 17:08:51 localhost kernel: 000] Mount-cache hash table entries: 512

Nov  9 17:56:25 localhost kernel: No module symbols loaded - kernel modules not
enabled.
Nov  9 17:56:25 localhost kernel: nitialized
(the latter may be a typo in kernel sources?)

Actually, there's a repeatable pattern here. Every time after "No module symbols
loaded", the next line is partially garbled.
Nov  9 15:21:18 localhost kernel: No module symbols loaded - kernel modules not
enabled.
Nov  9 15:21:18 localhost kernel:
