Bug#703673: Request to backport acpi changes to Debian sid for proper acpi child device handling

[piruthiviraj natarajan <piruthiviraj@gmail.com>]

Package: linux-image-3.2.0-4-amd64
Version: 3.2.39-2
Severity: important
There is a upstream linux kernel bug
https://bugzilla.kernel.org/show_bug.cgi?id=42696 which prevents the
Lenovo Y580/Y470/Y570 and Toshiba Satellite P870  devices unable to
find the Nvidia card through proper acpi device handling.
It has been discussed in detail in this thread as well at bumblebee
git page too. https://github.com/Bumblebee-Project/bbswitch/issues/2

It has been fixed since Linux kernel 3.9 rc2 through this patch
https://bugzilla.kernel.org/attachment.cgi?id=89731.
The bug applies to wheezy as well and backporting the new kernel
changes would fix the proper acpi handling.

I hereby request the kernel maintainers to backport these changes to
Debian wheezy.

Thank you,

Dr. Piruthiviraj Natarajan
