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. -- Keir
