Comment # 9 on bug 85107 from Marcel Witte

Today I tried to use radeon.dpm=0 to get the full performance, but I noticed
that with radeon.dpm=0 I get the CPU stuck errors again, even with
radeon.bapm=0. So the only way to boot without these errors is "radeon.bapm=0"
or "radeon.bapm=0 radeon.dpm=1".
