The shutdown sanity test that we previously saw on qemux86-64 in 2.6.37 have
started to re-appear reproducably on qemux86 in 3.4 in the Danny series. Until
this can be root-caused and fixed in the kernel, disable paravirtualisation
across all kernels and all qemu machines.

Make sure to cc me on linux-yocto patches, I noticed this by chance.

I'd rather keep this on for the -dev kernel, it is development for a reason and
we should leave this on as a leading edge feature.

Have we seen the failure on 3.8? Or only on 3.4?

I've only seen it on 3.4 but it's only occasionally hitting so that
doesn't really say a huge amount. I can re-send it for 3.4 and we can
continue to watch the AB -- if it doesn't re-appear on 3.8 then we
can try re-enabling it for qemux86-64 too.
