Oh, I don't want you to publish them, just check whether it's a specific one or more random. And maybe it helps in reproducing. > vainfo (latest git) shows: > libva: libva version 0.32.0 > libva: va_getDriverName() returns 0 > libva: Trying to open /usr/local/lib/dri/i965_drv_video.so > libva: va_openDriver() returns 0 > vainfo: VA API version: 0.32 > vainfo: Driver version: i965 Driver 0.1 > > the player is the latest mplayer hwaccel-vaapi branch (latest git) > http://gitorious.org/vaapi/mplayer/commits/hwaccel-vaapi > console command is mplayer -vo vaapi -va vaapi stream.mkv > > Is there any way to monitor rc6 state change, i.e. gpu/ring clock speed? > Maybe this helps to track down issues caused by rc6 state changes?
