Package: laptop-mode-tools
Version: 1.60-1
Severity: important
File: laptop-mode-tools
Dear Maintainer,
After installing laptop-mode-tools my laptop (a Thinkpad T420) wouldn't
shutdown. Every time I did shutdown -h now, it would reboot. I also
noticed that it just happened when it running on battery when on power
it would do as expected.
I was using the latest kernel (3.1.0) and then installed the one from
backports but it showed the same behavior.
My laptop has a fingerprint reader and when shut down, it's always on.
So, when I ussually shut it down the laptop goes completely off and then
the fingertip reader comes back on, so I can start the laptop sliding my
finger there. But when laptop-mode-tools is installed, the laptop goes
completely off and then the fingerprint reader comes back on and right
after that my laptop starts booting back on.
When I uninstall the package, and shut the laptop down, it comes back on
but on the next shutdown it starts working as espected.

This one is not reproducible in the latest 3.3 kernels as reported by
the users and has been marked as fixed-upstream [1]. I myself am on 3.3
kernel and have not seen this issue. I could have reassigned this bug to
the kernel team so that they backported the fix, but the bugzilla has no
patch attached. Finding the right commit that fixed the bug will require
bisecting the 3.3 release.
Still am adding the kernel team. Just in case they have any further
information.
