Hallo Uwe,

vielen Dank für Deine schnelle Antwort.

Am Montag, 16. Dezember 2013, 19:54:46 schrieben Sie:
> Ist das ein Debian-Kernel? Welcher? Welche Architektur setzt Du ein?

Ja, ein Debian squeeze, welches ich stets aktuell halte.

root@kether:/home/ponnath# uname -a
Linux kether 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux

Der Prozessor ist ein AMD Athlon(tm) 64 X2 Dual Core Processor 4200+
Die Grafikkarte ist eine NVIDIA QUADRO 410

> Hast Du https://www.kernel.org/doc/Documentation/RCU/stallwarn.txt gesehen?

Ja, und leider nur Bahnhof verstanden - oder nur so viel, daß man die Ausgabe 
dieser Meldungen mit verschiedenen Parametern beeinflussen kann.

OK, hier die Ausgabe der Meldung von gestern früh. Ist etwas länglich:
