[Xen-devel] Failure to boot default Debian wheezy (pvops) kernel on 4.2-rc2



I just tried to install Xen-4.2.0-rc2 on a Debian wheezy system, but
couldn't boot under Xen 4.2.  The box is an 8-core AMD, I think
Barcelona.  The wheezy kernel is 3.2.21-3, 32-bit version.

The problems seem to have started here:

And pretty soon degenerated into log message spamming of this sort:

The serial log is attached ("exile.log").

An earlier kernel I had lying around, 2.6.32.25 (perhaps one of
Jeremy's?) boots fine; the serial log is also attached
("exile-good.log").  It also seems ot have the WARN above, so maybe
that's not actually the issue.

Any ideas?
