Oh, and there's another issue with this driver I reported yesterday:
http://marc.info/?l=linux-kernel&m=136243374114892&w=2:

"Trying to free already-free IRQ 20"

which happens during suspend so it seems also related.

Rafael, what's the state of those patches here:
https://lkml.org/lkml/2013/2/4/185, are they ready to be tested or you
still have issues with them?

Thanks.
