Modified Files: src/sys/arch/xen/xen: xennetback_xenbus.c Log Message: Check that xvif(4) is not already connected before proceeding in the XenbusStateConnected mode. Under rare occasions, the xenbus watcher can fire multiple times, overwriting the I/O ring memory mappings with invalid values. This will lead sooner or later to dom0 panic(). Will ask for pullup. FWIW, xbdback(4) is not affected.
