As Chris pointed out that this might be related to our qemu instance in
the CIP lab. We had a look and found the attached kernel splat. This
seems not a guest but a host problem (which is Debian/6.1 based and not
6.10).

I think you can continue, ignore the test result for this 6.10 release
for now. 

We will investigate further. Let's see.

For completeness the kernel log of the host is attached. LAVA runs into
a timeout and marks the job as failed.
