When we start triggering suspends from event channels, I'd suggest something along the lines of wrapping the whole thing in a big fat suspend mutex, and running the suspend from a workqueue triggered from the interrupt or watch handler. And then deal with all the edge cases. J _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
