Modified Files: src/sys/dev/ic: esiop.c siop.c Log Message: Turn the "esiop_intr: I shouldn't be there !" panic into a printf followed by a return from the interrupt handler. The condition is triggered on some KVM virtual hosts, apparently harmlessly, and not panicing makes it possible to boot a NetBSD GENERIC kernel on those hosts. Also make the same change to siop to minimize divergence between siop and esiop. Fixes PR kern/48277.
