I get repeated crashes on Linux 4.7.5 on SKL, the CPU is i7-6700HQ and the GPU HD 530. This crashes X and drops me to the console, restarting X and attemping to use it leads to an unrecoverable crash (the console will not return either, but sysrq works). This happens when the system is idle and display power saving is on. It can trigger when the display turns off, at a random time when the display is off or when turning the display back on. Here is the log output, the first line seems to repeat whenever this happens so is probably related.

This appears to be a regression in stable, I can't reproduce this issue on 4.7.3. The only relevant looking commit in between is d18accc, I'll retry with it reverted.
I have the same error on Linux 4.7.6-1, with a different effect. After it, the laptop behaves in a very strange way where it only seems to process system events while I move the mouse cursor.

Can you test with latest kernel and report back?
The issue still exists on 4.8, but seems to be fixed in the 4.9 rc series.
If this still works can you mark this resolved and closed?
