AVM Fritzcard hängt sich weg

[Christoph Wickert]

Hallo!

Unter Fedora kann ich meine Fritzcard DSL nicht dazu bewegen, längere
Zeit fehlerfrei zu laufen. Dauerbetrieb ist nicht möglich, in
unregelmäßigen Abständen (mal nach 7 Stunden, mal nach knapp einem Tag)
hängt sich das Ding einfach völlig weg, sodaß ein Reboot angesagt ist.

Hardwarefehler schließe ich aus, der Rechner ist unter Debian Woody
schon 2 Wochen am Stück gelaufen, Dail on Demand, Zwangstrennungen etc.
kein Problem.

Hat einer eine Idee? Fedora lässt einen da ziemlich im Regen stehen,
Bugzilla ist komplett zwecklos, da capi zu den unsupported Modules
zählt, siehe:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=112605
