Description Ben Davenport-Ray 2017-04-05 19:40:44 UTC 
Kernel hangs hard whenever it has to do anything graphics accelerated or too cpu intensive (two laravel web server instances / opening chromium / opening YouTube on Firefox / I look at it too hard). It won't even let me switch to another console, forcing me to hard reboot. 

I am unable to see anything using `journalctl -xe` when my system goes down; either the log just stops or the file is corrupted, though I also don't know what I am looking for. 

I was able to confirm that it wasn't thermal overheating, and chip diagnostics say that it is okay. 

Linux 4.9.20
xorg-xserver 1.19.2

journalctl output

Command was 

    journalctl -axb -3

the third boot being one that froze.
Comment 5 Michel Dänzer 2017-04-11 08:41:29 UTC 
Did this not happen with an older version of the kernel or other software components?
Comment 6 splitt 2017-04-19 07:12:12 UTC 
Same hang here, same CPU : booting with kernel parameter amd_iommu=off solved the problem.
