That's mysterious.  My first thought is that this is a separate problem.

Is it ever stable?  What happens if you set dom0_mem to 4G or less?

Is the console responsive when the kernel hangs?  That is, can you type
"Ctrl-A Ctrl-A Ctrl-A" to get Xen, then enter debug keys?  '0' (zero)
should dump the context for dom0 and give some clue about where it is dying.

Thanks,
