k3b did "something" to my cd0 while tasting it and after that IDE activity LED was
constantly on and I got a never-ending stream of messages like the following:

ahcich5: Timeout on slot 25
ahcich5: Timeout on slot 26
ahcich5: Timeout on slot 29
ahcich5: Timeout on slot 30
ahcich5: Timeout on slot 1
ahcich5: Timeout on slot 2
ahcich5: Timeout on slot 5
ahcich5: Timeout on slot 6
ahcich5: Timeout on slot 9
ahcich5: Timeout on slot 10
...
and so on.
cd0 is on ahcich5.

This is head r196558.
