Hallo zusammen,
bevor ich das Upstream melde, wollte ich hier mal nachfragen, ob jemandem folgendes Problem bekannt ist.

Der Rechner ist ein
Acer Revo und läuft als Digital Signage Gerät 24/7.
Als ich heute morgen ins Büro kam, war die Kiste eingefroren:
Die Bildschirmausgabe (Flash-Anwendung auf Basis von ADL) war statisch mit zu großer Auflösung, sodass das Bild nach rechts und unten aus dem 1080p Monitor "raus lief".
Per SSH kam ich nicht drauf, also habe ich eine USB-Tastatur angesteckt, auf welche der Rechner auch nicht reagierte.
Nach einem Reset über den Power-Button habe ich dann entsprechend nachgeschaut, was das Problem sein könnte, und die beiden Traces oben in dmesg entdeckt.
Zu den Fehlern habe ich nur ältere Threads und
diesen, über ein Jahr alten Thread im Kernel Bugzilla gefunden.
Kann der System-Freeze und das komische Bild mit der o.g. Meldung bzw. einem damit aufgezeigten Bug im Grafiktreiber zusammenhängen?
