[SOLVED] Problem mit Kernel 2.6.36-1.slh.1-aptosid-686

(1/3) > >>

ralv:
Hallo Leute,

Mit dem o.g. Kernel bekomme ich Probleme mit einem externen USB-Laufwerk. Dieses hat eine separate Stromversorgung. Es lässt sich mounten und auch einwandfrei benutzen, z.B. für Backups. Wenn ich es dann jedoch über den KDE-Device-Notifier unmounte und anschließend ausschalte, wird meine KDE-Session beendet, ich lande auf der Konsole und sehe folgendes:

Das Verhalten ist reproduzierbar und tritt mit dem davor verwendeten Kernel (2.6.36-0.slh.8-aptosid-686) nicht auf.

devil:
kannst du es mal händisch umounten?

ralv:
hi devil,

grad probiert...derselbe fehler.

ralv:
kleiner nachtrag: der fehler lässt sich auch mit 2 weiteren externen usb-laufwerken reproduzieren.

Blackshine:
Ist mir vorhin mit einem USB-Stick ebenfalls passiert.
