AFAIK the rv610/630 and rs780 were the first with any kind of DPM hardware, so older chips (r600 and earlier) rely on the driver for all power management.
Ahh, that might explain things. I have a rv670 card. Do you know if DPM is available for that specific ASIC?
The firmware available for it dates back to 2009 (r600). I thought that I could not use DPM due to a missing updated firmware, but the problem might be deeper (the card having no DPM hardware).

AFAIK the rv670 does have DPM support but does not require additional microcode.

Thanks in advance.
I can't tell what DPM does on my RV670. It claims that it initializes (and doesn't show any errors) and I can read the debugfs information, but it idles at 84C. With dynpm/fglrx/windows it idles at high 50s~low60s.
Out of curiosity is there an alternative way of enabling it?? My setup is a bit weird and passing command line arguments is a bit of a pain.
If you built radeon as module, then that option can be added to /etc/modprobe.d/ (or some distro specific location). Otherwise, you can set in your kernel config,
Thanks!
I'll trying this out again soon and report back.
Just tested with the latest work... Still the same issue. Machine freezes with a white screen when it was supposed be modesetting.
If I remove "radeon.dpm=1" from the kernel command line, everything works (but no DPM).
The crash ocurrs so early during the boot process that nothing gets logged at all in journalctl. It's like the boot never happened...
