I have the same problem. Output from radeon_pm_info when the state is supposed to be set to high:

uvd    disabled
vce    disabled
power level avg    sclk: 30000 mclk: 126000

Some relevant dmesg output:

Forgot to mention my setup. I'm using an ASUS R9 290, a Linux Mint base system tracking the xorg-edgers PPA, and kernel 3.19-rc3 from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-rc3-vivid/

I have the latest linux-firmware.

The mclk began changing after I upgraded from 3.18.1, but the sclk is still stuck at the lowest level.

possible fix

The attached patch should fix the bug.

Seems to have fixed the issue for me. However, I only did some quick tests, so perhaps leave this bug open for a few more days so I can test if there are still some corner cases where it breaks.

Thank you so muck Alex! :)

It works beautifully here on my R9 290. Thanks!

I've been using it for a few days now. It seems like the reclocking issue is completely fixed for me.

I'll close this bug as it seems to work flawlessly for Brooks too.

Thanks again Alex.
