Hi,
this seems to be the same problem I had, when registering an irq with UIO.

I did use irq_create_mapping, to initialize this struct. However I
have no idea if this was right. It seemed to work at first, but I'm
encountering problems now, however I don't know if they come from the
kernel, or UIO interrupt handler. I did this for some test, but irqs
are something you want to be sure they work correctly.
So maybee someone could clarify this as we already raise this issue.
What processor are you using Sebastien? My one is a 405EP
Best Regards
Markus
