Comment 11 for bug 1538741

I'm still bisecting, it's probably either
- fcfb5aa246c80df8b0a2ccadd7284b4c189149b0 ( https://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack/commit/?id=fcfb5aa246c80df8b0a2ccadd7284b4c189149b0 )
or
- 09af0842dac496aae363719c449cb88dcc953299 ( https://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack/commit/?id=09af0842dac496aae363719c449cb88dcc953299 )

from the mainline-crack repository ( https://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack ) . AFAIK my Lenovo T60 doesn't have an i915 chipset so it's probably the vblank commit.

The latest released kernel, 4.5 ( http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/ ) still has freezes for me.
