I've narrowed down the problem a bit more, and I don't think it's a kernel bug but maybe something with KDE or X Windows...
The system will shutdown and then power off when I do the following:
Power on the laptop
CNTRL-ALT-F1 to bring up a console
Logged in normally
Issued the command - "sudo shutdown -h now"
It then shuts down and powers off the laptop
However, when I click on "K Menu -> Leave -> Shut Down" in KDE (this is Kubuntu 11.10), the system will halt, but not run the poweroff command.
I edit /etc/default/halt and add a line to remove the Intel sound module so it now looks like this:
# Default behaviour of shutdown -h / halt. Set to "halt" or "poweroff".
/sbin/rmmod snd_hda_intel
HALT=poweroff
However, the system won't power off when shut down from KDE.
I'm attaching my /var/log/syslog if that will help. I upgraded laptop-mode-tools to 1.58, which resolved the "Unhandled kernel version" error, but doesn't resolve the poweroff issue.
