[XenARM] Xen with Cortex-A15 - Guest data abort: Translation fault

[Jenny Smith <smithjenny183@xxxxxxxxx>]

Hi,

I'm running the latest code from
http://xenbits.xen.org/gitweb/?p=people/sstabellini/xen-unstable.git/.git;a=shortlog;h=refs/heads/arm-tools-1.
I compiled both Dom0 and Xen. I use a Versatile Express board model
with a single CPU Cortex-A15.

For Dom0 I used the vexpress-dt branch of
git://xenbits.xen.org/people/dvrabel/linux.git and built it as
described here:
http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions

However, when Dom0 boots, I get a guest data abort translation fault
error. See the message below.

Has anyone else seen this?

Thanks
Jenny
