Created attachment 130119 [details] 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 :/
I just tried to quickly reproduce the problem using timer delayed xset usage and turning off monitor and unplugging it... but no oops and no graphics stack corruption... (Well... at least *that* is good news) So it will take some better testing to reproduce it... Hopefully I won't have to resort to leaving my computer on overnight again with original setup of sleep after 30 minutes and monitor turned off...
