Hallo,

ich bin bei meinem MediaCenter vor kurzem von analogen auf digitalen Kabelempfang umgestiegen. Erfreulicherweise konnte ich die Sticks erfolgreich mit MythTv unter Ubuntu 14.04 an den Start bringen. Leider habe ich seit dem Umbau täglich mindestens einen System-Freeze. Häufiges Zappen scheint die Zeit zum nächsten System-Freeze zu verkürzen. Um die Ursache einzugrenzen, habe ich per Remote-Connection das syslog verfolgt und vor dem Freeze folgende Meldung erhalten:

Da als verursachender Prozess "mediasrv" ausgegeben wird, hoffe ich, hier Hilfe zu erhalten. Es scheint auch einen Unterschied zu machen, ob ich einen oder zwei MediaTV Pro Sticks betreibe. Ich benutze die Version 2 nun problemlos 2 Tage. Ob es einen Unterschied zwischen Version 2 und 3 gibt, beobachte ich gerade. In circa 2-3 Tagen kann ich dazu mehr sagen.
