Hi All,
after today's sync with amd-staging-drm-next branch I have problems with my
Mullins APU Netbook.
Kernel log is flooded with "[TTM] Erroneous page count. Leaking pages."
message.
Bisected, and it seems that "drm/ttm: fix start page for huge page check in
ttm_put_pages()" commit is causing this.
git bisect log:

Yeah, that is a known issue and already fixed in amd-staging-drm-next.
You just need to wait for the public mirror to update.
