That error was from a booting 2.5.62 and i do get the warnings about
missing error handling.

I'm not concerned about that, that was peripheral damage from another
patch (affected irq handling), the difference being is that with 2.5.62 it boots
after printing those errors a couple of times, but with 2.5.63 it doesn't.

I'm currently using it with the following devices and survives general
usage.
