do you have radeon.dpm=0 in smoe /etc/modprobe.d or somewhere like that file?
No: # grep -nHr radeon.dpm /etc/* /etc/default/grub:9:GRUB_CMDLINE_LINUX_DEFAULT="quiet radeon.dpm=1"
What's the result of "cat /sys/module/radeon/parameters/dpm" when you don't specify the "radeon.dpm=1" on the kernel commandline?
$ cat /sys/module/radeon/parameters/dpm -1
I verified with
$ dmesg | grep -i "command line" && cat /sys/module/radeon/parameters/dpm [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-3.16.0-rc6-citadel+fdo-att-104101 root=/dev/mapper/citadel--vg-vol--root ro quiet [ 0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-3.16.0-rc6-citadel+fdo-att-104101 root=/dev/mapper/citadel--vg-vol--root ro quiet
that I removed the radeon.dpm=1 from the kernel command line before booting. Kernel version is Git:~agdf5/linux:drm-next-3.17-rebased-on-fixes:fa78380797 + patch from attachment 104101.
