Kernel Bug | 2.26.26-2-amd64
Hallo,
Seit dem Update auf den 2.26-2er Kernel friert mein System regelmäßig alle 2 -3 Tage ein.
Auszug aus dem Kernel.log:

Die Logs sind voll solcher Einträge. Nicht nur der Apache-Dienst ist betroffen.
#517449: linux-image-2.6.26-1-amd64: SCHED_IDLE issues (tasks blocked for more
than 120 seconds)
#517586: "INFO: task * blocked for more than 120 seconds" causes system freeze
Wie kann ich den Bug umgehen? Gibt es einen Patch hierzu? Kann ich unter Lenny einen neueren Kernel installieren?
Danke vorab.
Grüße
Kadir
