--- Comment #11 from Andrey Grodzovsky <andrey.grodzovsky at amd.com> ---
I see from the log that your failure was on 0 order allocation (1 page) in zone
NORMAL but this ZONE still had enough 1 page blocks and even larger blocks to
fulfill your request so that strange.
The only problem I see from the logs is that your free memory in zone NORMAL
was lower then min watermark watermark, which AFAIK this should have triggered
kswapd to start swapping out memory. I do see you have already some pages in
swap so maybe that it.
Any way , I can't understand why exactly that failed from the logs. Possibly
some memory leaks. 
Please add cat /sys/kernel/debug/dri/0/amdgpu_gem_info immdialy before and
after suspend operation to see how much memory the driver allocated.
I will try to ask people from #mm about your log.
