I'm already using newest git mesa (Oibaf graphics drivers ppa). I also have tied self compiling the git mesa driver but no change to hibernate. However I disabled the radeon DPM power management with radeon.dpm=0 in kernel command-line and it fixed the hibernate! I still see awful lot of this '[drm:si_dpm_set_power_state [radeon]] *ERROR* si_set_sw_state failed' error in dmesg tough. Also bad is that I miss the automatic DPM..

If you set radeon.dpm=0, you shouldn't see any of the dpm error messages in your log. Make sure the parameter setting actually got picked up.
