Bug ID: 100109 Summary: Graphics Lockup if monitor disconnected and then set into standby Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu-pro Assignee: dri-devel@lists.freedesktop.org Reporter: kierangrant@linux.com
Created attachment 130119 --> https://bugs.freedesktop.org/attachment.cgi?id=130119&action=edit 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 :/

--- Comment #1 from Kieran Grant kierangrant@linux.com --- 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...
