--- Comment #2 from Arkadiusz Miskiewicz <arekm at maven.pl> ---
Looks like GPU is innocent.

This machine has 8 cores (4 normal and 4 HT). I was using maxcpus=4 (due to
Dell XPS 15 bugs like whining coil).

My current theory is that after resume from ram these 4 HT cores are eating
power. Why? Because if not using maxcpus option then everything fine and there
is no issue at all.

It could be called kernel bug to not shut up these additional cores after
resume but well...
