Aug21 fermmy resume syslog full (after resume)

This morning, ~8:40AM EST Aug21 2019, resumed my system from suspend.
Normally it just comes back AOK, but today it hung. The screens were all wonky (mostly grey with a speckle of colour), disk was going bonkers, couldn't SSH into it;  sometimes this happens and I just walk away for 10 mins and come back, sometimes it fixes itself, sometimes not.  Today I was not patient and just reset it after ~3mins of waiting.

Took a look at the previous boot system log and there were numerous AMDGPU related failures.

snippets include:
