The results are that for all versions from 18.0 to mesa-dev I get the same problem that Android boot does not complete, but the GUI restart does not happen always at the same time and in the same way. In most cases the bootanimation is interrupted, in some others GUI freezes at Status Bar drawing. Reiterating the GUI restarts for a while I have collected dmesg and logcat with drm.debug=30 in order to trace for problems happening during several attempts Could you please have a look, because GPU hang is not systematic, I'd like to understand what is causing SurfaceFlinger process to Hang.
