Yes, both badnesses A: “immediate black screen that can be recovered from” and B: “eventual freeze” were introduced by the same commit. Another thing I should have been more clear on: the external monitor is necessary to reproduce A and so far B hasn’t happened with it unplugged either. (Could it be possible there was some sort of latent bug in the i915 driver that this commit just made surface?) *** Bug 201091 has been marked as a duplicate of this bug. *** *** Bug 201153 has been marked as a duplicate of this bug. *** *** Bug 202675 has been marked as a duplicate of this bug. *** We have quite some EC changes recently, can you please check if the problem still exists in the latest upstream kernel? I think this should be fixed in the latest upstream kernel. please feel free to reopen it if the problem still exists in the latest upstream kernel. |
