i.MX53 system not responding - using Magic KeyReq

chrisruehl — Fri, 01 Mar 2013 06:22:31 GMT

Hi All !

may you had stuck in a similar problem before and give me a hint on this.

We running a 2.6.35.14 kernel with freescale patches and system become randomly not responding

serial console, fb all frozen.

Magic KeyReq ALT+CTRL+SysReq+<...> give me some idea what happened (see attachment):

We have 2 Gstreamer pipes running a) Audio (audio-pipe) b) Video (video-pipe) both pipes run in its own thread and are fully

independent. If a video is running on the video-pipe, we mute it by set volume to 0 and use the audio-pipe to play an announcement.

Randomly its happen that the system hangs. We get out some infos from the Kernel using the SysReq (see below)

may you can bring light into darkness.

Complete prints attached.

cheers

Chris
