CPU spikes in media_addon_server
|Reported by:||tangobravo||Owned by:||nobody|
My laptop gives occasional (a bit random, but usually 2 or 3 per minute) 100% CPU spikes in threads within the media_addon_server, often the "Yeah baby, very shagadelic" but sometimes the "Intel HD Audio control" thread. Happens with both HDA driver, and OSS (with hda moved to desktop). The spike lasts for a couple of seconds, and as these are real-time priority threads, seem to freeze the entire system.
Attached an output from scheduling_recorder showing the event. Also a syslog and listdev.
