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.
