Public bug reported:
After upgrading to linux-image-2.6.31-21-generic last week (karmic-
updates repository enabled), all of our Gateway E4300 machines end with
a segmentation fault instead of shutting down properly and completely.
Several other models of hardware are unaffected. This is consistently
observed across several hundred machines.
The 2.6.31-21.59 changelog includes this:
* clockevents: Prevent clockevent_devices list corruption on cpu hotplug
- LP: #509730
Reverting to linux-image-2.6.31-20-generic prevents the problem, as does
booting with nolapic (but you lose SMP, or hyperthreading in the case of
the E4300). Also, rebooting does not exhibit the problem, only halt.
This appears to be the same or a nearly identical bug reported in the last few
months in other distros:
http://bugs.gentoo.org/show_bug.cgi?id=312767
http://lists.opensuse.org/opensuse-bugs/2010-02/msg01527.html
https://bugzilla.kernel.org/show_bug.cgi?id=15005
https://bugzilla.redhat.com/show_bug.cgi?id=558231
But this is a new regression for Ubuntu.
On the screen the message begins (hand transcribed by someone else):
* Stopping early crypto disks...
...done.
* Will now halt
