Also, in the last set of builds, despite booting with "nopat", we see:

https://autobuilder.yoctoproject.org/main/builders/nightly-x86-lsb/buil
ds/637/steps/Running%20Sanity%20Tests/logs/stdio

Central error: [    9.298049] Failed to add WC MTRR for [fd000000-fdffffff]; performance may suffer.

Why we only see this on the lsb run I don't know but that address looks
like the one causing problems elsewhere with PAT. It could therefore
look like this is related to uvesafb.

Cheers,

Richard
