No, just that you've found a bug I think.

I'm copying the devel list here to see if anyone has any clues.

In a normal running system in "xl dmesg" or you can configure
xenconsoled to write it to a file. But with a crash on boot it is too
soon for all of that, the solution is usually to use a serial console
(see the wiki), but a photograph or just noting to the error as you've
done can work too.

I'll leave it to others on the dev list to request a serial log or a
photo if they think it would be useful to have the additional
information (e.g. register state, stack addresses etc).

Ian.
