I have some vague recollection that we had some issues there, but
nothing specific pops up in my mind. Do you remember some places
worth looking at ?
By the way, I also tried this with the SDIO interrupt problem, which
would fit the "things go horribly wrong for no good reason" category
rather nicely, but it didn't solve it :-( The patch that illustrates
how to switch a function block's interrupt from edge to level is
below.
