Do you know if this bug is fixed in kernel 3.13.2 version ?
I am still using the 3.12 kernel but am forcing dpm with radeon.dpm=1 kernel paramater. My HD6670 runs cooler and much more reliably with dpm enabled. I have not tried the 3.13 kernel.

3.13.3-1-ARCH doesn't show that problem anymore.
Currently, I only see one related warning in dmesg:
[ 7.471317] pci_pm_runtime_suspend(): radeon_pmops_runtime_suspend+0x0/0xa0 [radeon] returns -22
Didn't note any negative side effects.
