Oh yeah, I really want that for libata. Routing is only part of the
problem and flaky IRQ is something we have to learn to cope with.

I think things would be better this way. If the drives (both cd and
hard) / input devices are not accessible, most people would simply
give up rather than reporting, and many cases are transient problems
which happen only once in the blue moon.

It would be great if some kind of automatic reporting can be used
(similar to kerneloops?). Hmm... maybe make the warnings scarier?
