Hello,
After upgrading kernel from 3.1.5 to 3.2.0 the notebook cannot wake from suspend to RAM properly. The problem stays even with 3.3-rc1.
It wakes, but the screen is blank and computer needs to be rebooted.
When woken, computer is working otherwise (can ping it, ssh to it etc.)
I git bisected it to commit cd9dde44f47501394b9f0715b6a36a92aa74c0d0 is the first bad commit commit cd9dde44f47501394b9f0715b6a36a92aa74c0d0 Author: Adam Jackson <ajax@redhat.com> Date: Fri Oct 14 12:43:49 2011 -0400
drm/i915/dp: Fix the math in intel_dp_link_required
The previous code was confused about units, which is pretty reasonable given that the units themselves are confusing.

Reproducible: Always
Steps to Reproduce: 1. suspend to RAM 2. start the computer Actual Results: Screen is blank
