Hi,
I found last week that my system with radeon RS880 doesn't resume from suspend with radeon dpm enabled with kernel 3.12-rc5. Then i tested with kernel 3.12-rc2 to 3.12-rc4 this weekend with the same result. If i remove radeon.dpm=1 from the command line in grub then everything works fine (like always on this system). It works also fine with kernel 3.11 with dpm enabled. I found no errors in dmesg an Xorg.0.log, both are attached. The kernels are from the ubuntu kernel mainline ppa and i also try with a self compiled vanilla kernel.
