Xenbuilder2 and PPC seem to be a bit borked

[Robert Scheck <robert fedoraproject org>]

Hello folks,

it looks like Xenbuilder2 and PPC at buildsys.fedoraproject.org seem to be
a bit borked, I've succeeded builds (from build.log) but get an build error
where none is, e.g. job 35622 or 35623. These jobs are failing at more or
less random positions when requeuing them. Can we get rid of this issue,
please? :)


Greetings,
