It is quite stable in that the secondary processors reliably join the
idle domain and wait for free pages to scrub, handling 0x980 interrupts
with no problem.

What's this 980 exception?

However, the domU's sometimes hang during initialization. When the domU hangs, it seems the whole machine freezes, including the serial console.

Most common cause of this is hanging the U3/U4.  Do you have a hardware
debugger to see where this happens?
