[Pkg-acpi-devel] Bug#601368: acpi-fakekey: kernel oops on halt or reboot

[hugo vanwoerkom]

Package: acpi-fakekey
Version: 0.137-5
Severity: normal

Upon system halt or reboot I get a kernel oops that points to acpi_fakekeyd.
This is with the latest Sid kernel 2.6.32-5-686.
The system hangs afterwards and it messes up grub so I have to grub-install
from a live CD.
This is what syslog shows:
