Console drops into the same stack trace in both cases.
Jeremy: Any ideas could some recent change in pv_ops dom0 kernel cause usb stuff to stop working with >4096M of dom0 memory?
dom0_mem=4096M works dom0_mem=4097M fails with stacktrace
Boris: What was the last kernel that worked without backtraces? Also, does that same kernel work as baremetal (without Xen) ?

System boots up with dom0_mem=4096M.
Does it boot up with dom0_mem=4097M ?
How about dom0_mem=6144M ?

Call trace:
OK. How much memory you have?
Does it happen with dom0_mem=2048M? Does it happen with dom0_mem=4096M?

I have to specify dom0_mem, otherwise stack trace.
Hmm... what kind of stack trace you get without dom0_mem specified?
