The commit 448f53a1ede54eb854d036abf54573281412d650 drm/i915/bios: Reverse order of 100/120 Mhz SSC clocks
causes a regression on a SandyBridge machine here. The laptop display (LVDS) becomes blank. Reverting the commit fixes the problem.
The question is whose BIOS is wrong? The Lenovo U160's or the Sandybridge SDV? And why does it work for that other OS? <Insert rhetorical question of the day here.>
