[Xen-devel] Using xen-unstable, dom0 hangs during boot

["Nadolski, Ed" <Ed.Nadolski@xxxxxxx>]

I'm running Fedora 12 (kernel 2.6.31.5-127.fc12.x86_64) on a Dell T7500 Xeon 
with VT-x and VT-d. After building xen-unstable and rebooting, the dom0 Linux 
hangs a few seconds after it gets control from Xen, and I have to power-cycle 
to recover.   Here are the last messages before it hangs:

[    2.766882] loop: module loaded

<<hangs at this point>>

Thoughts?  Any grub parameters I should try for Linux and/or Xen?  Any further 
info I can provide?

Thanks,
Ed
