--- Comment #244 from Alex Deucher agd5f@yahoo.com --- Created attachment 106085 --> https://bugs.freedesktop.org/attachment.cgi?id=106085&action=edit workaround for basic enablement
As per feedback from the last few comments the attached patch forces the performance level to high rather than auto which should fix the stability issues and lower power usage due to clockgating, etc. and enables dpm by default for rv6xx.
