Hi,

I think my commit was identified as bogus and tglx is going to revert 
it. The problem is that I force ONESHOT mode for all threaded IRQs but
there are also others without the flag which is not allowed.

I was trying to check something but I don't get my board to boot. Could
you please try to boot with the patch reverted and paste me the
the output of 
 cat /proc/interrupts | grep 74 ?

I *think* that the flow handler is level (I can't find evidence of it
beeing edge, and omap_alloc_gc() is the place installing it).

So could you please gather additional debug info with this patch?

%pS should resolve the function names.
