Hallo zusammen,
ich hab hier ein sehr seltsames Verhalten, dass ich nicht erklären kann.
Mein Debian-Server lief früher auf lenny, nun auf squeeze bis vor einer Woche absolut stabil. Dann gab's einen freeze ohne Reaktionsmöglichkeiten (vgl. Bild)
Jetzt ist das wieder aufgetreten, aber ich konnte noch mit Strg+Alt+Fx auf die virtuellen Konsolen umschalten. Beim Versuch mich einzuloggen kam dann folgende Meldung:

Ich habe nicht's an der Hard- oder Software verändert außer eine (defekte) RAID-Platte getauscht und die üblichen debian-updates installiert.
Außerdem hab ich noch folgendes Problem (auch aus heiterem Himmel) - vlt. haben die ja was miteinander zu tun?
Ich hab eine Medion-DVB-T-Karte im Server (saa7134). Die lief bisher auch immer problemlos. Als ich heute mal was schaun wollte lief vdr nicht weil es unter /dev/ kein dvb mehr gab. Das ist einfach weg.
