kernel output captured from the serial line.

Playing video hangs X-Server with showing scrambled picture, sound still
playing.

System hangs after some time playing mostly when playing a recorded DVB-S-SD
stream via VLC. Happened also with other videos and players.

This left the system showing a distorted version of the last shown frame from
the video. Most of the time it is a chess board like pattern.
Sound is still playing regularly.
A ssh connection is still possible.

Playing the exact same video again later works without problem.


Kernel output shows at this time following:
