There are known issues with 2.6.15 as an x86_64 dom0 -- that's why its not 
checked into the tree. This sounds more serious than the other problem that has 
been observed, though.

Put 'noreboot' on the xen command line, and don't start X in dom0 so that you 
get an oops message (or connect a serial line).

using a debug=y build of xen would be best.
