Hi,
today's git checkout boots fine on powerpc32, but has this message during
bootup:

The system is running fine so far and has before with 3.2.0-rc7, without
that warning. The "vgchange" could be the result of some LVM2 initscripts
(lvm2-2.02.66-5 are installed on this Debian/stable system), but there are
no LVM disks anywhere on the system.
Full .config & dmesg: http://nerdbynature.de/bits/3.2.0/
Is this BUG something to worry about?
Thanks,
Christian.
