--- Comment #7 from Ed Tomlinson ---
The only setting I cannot revert in the patch is:
pi->mclk_dpm_key_disabled = 1;
To avoid humdreds of: radeon 0000:01:00.0: GPU fault detected: 146 0x0aa20804
and 147 type errors I had to add: export R600_DEBUG=nohyperz in the X startup
as documented in: https://bugzilla.kernel.org/show_bug.cgi?id=66981
Also found some funny stuff to do with primary and secondary graphic cards.
booting with the primary as the builtin hd4600, with no radeon specific stuff
in the kernel command line does NOT enable the dpm on the secondary radeon card
and trying to use radeon.dpm=1 causes the X startup to stall. Note in all
cases the a xorg.conf file selects the radeon card to be used.
