Geert,

Thanks for giving it a spin, especially on a platform as different from
ours as the PS3.

Before I dig more into what happened, I was wondering if you could tell
me a bit more
about your environment, particularly how you supplied the filesystem to
the kernel and
your mount commandline (also, if you used a boot commandline, what it was.)

My first guess would be a ppc64 compiled UML session, but I'd like to be
a bit more sure.
