It's bizarre that only you have seen this crash. It should be easy to track
down though. If you're happy to modify C code, can you try adding:
 printk("***TICKER_INIT %d %d\n", cpu, spc->ticker.cpu);
To csched_start_tickers() in common/sched_credit.c, immediately after the
line 'spc = ...'.

Alternatively I can send you a patch. The extra message should come out
twice immediately before the crash message and it would be interesting to
know what the messages say.

Also, the xen-syms file that matches the crash-message JPEGs you linked to
would be interesting. Perhaps you could zip that up and send it to me
privately if you still have it.
