[Xen-devel] Latest pvops hangs on boot

["Williams, Mitch A" <mitch.a.williams@xxxxxxxxx>]

Looking for a little advice here.  I've compiled the latest xen-unstable tree 
along with the latest pvops kernel from Jeremy's git tree.

Xen boots and loads the Linux kernel but then the system spews a bunch of 
errors and hangs.  I've set up my serial cable to capture the log, which is 
appended to this email.

This is a SuperMicro Nehalem box, nothing funny hardware-wise. The kernel boots 
fine on bare metal.

My current .config is attached. I've been tweaking config options for three 
days and haven't had any luck. Any ideas?

Thanks,
Mitch
