[LENOVO E595] Black screen on resume!
Submitted by Tesla Neumann

Suspending the laptop is not the issue I am experiencing but waking the laptop after suspension is what breaks. The laptop wakes up to a black screen without a functioning system, not even CTRL+ALT+BACKSPACE works. The issue is similar to https://bbs.archlinux.org/viewtopic.php?id=249510 and therefore I have tried all the solutions mentioned in that thread (before knowing of its existence). I also tried the Early KMS solution suggested by the owner of that thread, which I did not think of and the result remained the same. Solutions mentioned in https://wiki.archlinux.org/index.php/Laptop/Lenovo#E_series has also been tried but the problem remains unsolved.
Something worth mentioning is that the laptop has to go through suspension and waking up twice for the system to return to normal, but this solution works 20% of the times and has unfortunately caused me loss of important data.

From the above log files, V1del (https://bbs.archlinux.org/viewtopic.php?pid=1873276#p1873276), was able to identify crashes in my AMDGPU driver thus leading me to create this bug hoping for a fix!
