Various log files
I got a Kernel Oops from with AMDGPU-PRO for Ubuntu 16.04.2 LTS x86-64 version 16.60 after unplugging and plugging in my HDMI display...
Computer was left on overnight to do some long IO operation... before I left it, I turned monitor off... at the time my MATE display settings was to put monitor to sleep after 30 minutes... so I guess it tried that after 30 minutes...
Next day... I got no graphics response... after trying various F-n combos... I eventually tried some SysRq keys to force text console... but stock Ubuntu SysRq limit was in effect doh...
That is when as a last resort thought to unplug and re-plug in monitor... in hopes that would magically do something... it did something alright...
I got Kernel OOPS at that moment... it was early morning for me :|
Attached is a snippet of my syslog plus various ls* outputs...
I have a MSI Radeon RX480 8GB
I will see if I can manually reproduce the bug to get a Xorg.log file... I forgot that one and old one is now gone :/
