Re: [Xen-devel] Kernel panic while compiling kernel

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

This part of the trace indicates that it's a Xenolinux problem -- it's
trying to pin the same page multiple times (a bad thing). Hmmm...

An alternative is that Xen has misparsed the comamnds coming down from
Xenolinux. 

If you use our pre-built Xen/Xenolinux (a link near the bottom of
http://www.cl.cam.ac.uk/Research/SRG/netos/xen/downloads.html), can
you still reproduce the error?
