Can you perform on additional test. Can you test v3.7-rc1:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc1-raring/
If v3.7-rc1 has the bug, I will bisect between v3.6 final and v3.7-rc1.
If it does not have the bug, I'll bisect between v3.7-rc1 and v3.7-rc2.

We next need to identify the first v3.7 release candidate that
introduced this bug.
Can you test the following kernels and report back:
v3.7-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc4-raring/
If v3.7-rc4 does not exhibit the bug then test v3.7-rc6:
v3.7-rc6: http://kernel.ubuntu
In http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/ it is
working properly.
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/ has the bug.

I'd like to perform a bisect to figure out what commit caused this
regression. It would be very helpful to know the earliest kernel where
the issue started happening as well as the latest kernel that did not
have this issue.
Can you test the following kernels and report back? We are looking for

The bug remains valid. And has 6 votes other than myself. It just means
other people (like you Anmar) will have to do the testing as requested.

This is still a problem on the X1 carbon even with the latest BIOS

in 13.04. I am happy to test.
