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..
