--- Comment #5 from Anton Herzfeld <antonh at gmx.de> ---
The following patch fixes the issue with boosting again:

https://cgit.freedesktop.org/~agd5f/linux/commit/drivers/gpu/drm/amd/powerplay/hwmgr?h=amd-staging-drm-next&id=7d59c41b5150d0641203f91cfcaa0f9af5999cce

however it also seems to expose the issue in mclk not going down again once it
has boosted.

just to clarify the issue occurs when using manual OD on mclk since kernel 5.1.
