Comment # 6 on bug 59903 from Michael Lange

* today i recompiled mesa from master git (tree   
d276e9294d1f1218e374d43c1320b376ee265ad4) and linux-3.8.0-rc5
* xbmc is starting and working fine again
* the flip errors still appears in /var/log/Xorg.0.log
* with "echo 2 > /sys/module/drm/parameters/debug" nothing special in dmesg
(watched a 40min-video)
* "echo 1 > /sys/module/drm/parameters/debug" gives a bunch of lines (see
attachment dmesg_debug_1 )
