Shouldn't the device be able to specify an all-or-nothing request?
Perhaps something that needs fast interrupts will cause much hair pulling if it doesn't get one becasue of latency issues messing up the hardware. If the bus didn't grant a fast interrupt it could then declien to attach, perhaps spitting out a meaningful error message at the same time.
True, no need for an error message, but I suppose one could do something like this then:
Of course there's no need for an error message, everyone installing FreeBSD should be able to look at the kernel sources for his driver and figure out what's wrong with it.
If you get an error in attach(), you will return it back up the chain and device_probe_and_attach() will output a message such as:
foo0: attach failed - returned 6
or some such.
