It's probably not much to go on, but I was able to capture a kernel/xen
boot log over serial. Unfortunately it doesn't look like a backtrace (or
any indication of a problem) was able to be captured. AFAICT all logging
just stops after line 388.

Regardless, the captured bootlog should be attached with hopes that it
may be helpful
