Hi Jens,
Are you running rc-8. This seems to be a rescheduling issue.

Quoting the warning above:
cdrom Pid: 6998, comm: halt Not tainted 2.6.31-rc8 #105
yes :-)

Hmm, maybe some race condition happens...
Add Ingo into Cc:.
Your .config and dmesg are appreciated.
Thanks.

I'll send in the .config tomorrow when the box is up again, but
unfortunately I cannot post a full dmesg from this box. If there's
anything specific you want to look, I can post that. Otherwise I'll
probably try poking at this a bit, when some idle time appears.

I'm also seeing this following a system halt on the released 2.6.31 kernel
running in a qemu-kvm virtual machine, although there's no warning during
reboot there:

Is this likely to be a harmless warning or indicative of a more serious
problem with this kernel version (or config)?
