retitle 775812 linux-image-3.16.0-4-amd64: HP EliteBook 840 G1 laptop
fails to halt/poweroff after 3.16.7-ckt2-1 upgrade
thanks
For the kernel maintainers: according to the user's report and his
aptitude update log:
Last known-good version: 3.16.7-2
First known-bad version: 3.16.7-ckt2-1
Synopsis: System will not power down if WoWLAN is enabled in BIOS/UEFI
(platform default!). System will properly power down if WoWLAN is
disabled in BIOS/UEFI. This is a regression in the CKT stable kernels.

Thank you.
It was a quite large update run, but you did update the kernel, which is
the main suspect for this type of regression, anyway... so that's likely
it.
Other suspects (but very unlikely ones) from your update log: packagekit
and grub2-pc.
I will reassign this bug report to the kernel. It is likely caused by
some change in either the shutdown path, or the wlan driver or
subsystem.
If it at all possible, please attach to this bug report the kernel boot
logs of 2014-12-14, 15 and 16. They're usually either in
/var/log/dmesg* (if they have not been rotated out yet), or you'll need
to extract the relevant sections of /var/log/kern.log*.
Please also attach the output of "lspci -v -v" (run as root).
Let's hope the kernel guys can track down the problem and fix it. I
understand it would be easy for you to reproduce the problem if they
need more data.
