Bug#516209: kernel bug: kpowernow_k8/kondemand
Package: linux-image-2.6-amd64
Version: 2.6.26+17
Severity: normal
Description:
After installing Lenny as well after upgrading from Etch the system
spontanously crashes. May correlate with this kernel bug, although
this bug also seems to occur without crashing the system. Anyway,
using option acpi=off the system is stable (so far).
