solution (on the mainline kernel): git revert 49218c83e25b6f0708f246b07d570b2c43a98223 The problem is caused by the commit 49218c83e25b6f0708f246b07d570b2c43a98223 "drm/i915/dp: Link train Fallback on eDP only if fallback link BW can fit panel's native mode". I have not dig into this code, but only tried is reverting helps. It does. The problem is gone without this commit. *** This bug has been marked as a duplicate of bug 109398 *** |
