I haven't hit this crash. And Kuwamura-san's test seems that
he haven't hit it either. Kuwamura-san, is it correct?
Hmm... it seems to depend on hw configuration?
I'm inclined to suspect masking/unmasking interruption race.
event channel issues? But that's just only my very vague guess.

The difference between 18832 and 18860 means the merging xen-unstable
into xen-ia64-unstable.
Looking the log, I suspect linux-2.6.18-xen instead of xen.
Could you provide the linux c/s which corresponds to 18832 and 18860?

thanks,
