Comment # 3 on bug 110822 from Gobinda Joy

Thanks for the reply.

By today's standard my whole system spec is slow to be honest.

But slow ram speed shouldn't cause this problems with powerplay. As I can run
the card fine with load or idle with kernel version 5.0.17. It seems to me the
new commits from AMD for kernel version 5.1 is to blame. But I can't say for
certain.

Interestingly enough if I use amdgpu.dpm=0 to disable dynamic power management
kernel version up to 5.1.6 works just fine except crappy performance when under
graphics load.

I was curious so checked out the commit log on amd-staging-drm-next branch. And
I see some reverts of powerplay related commits.

I am currently waiting for this to getting merged with master branch.
