This could be many different things.  The first thing that comes to my mind is that the scan results are the first thing that comes as a real interrupt (before this all the interrupts are polled).  So are you sure the interrupt line is working properly?

The interrupt line it seems to work properly. I put a printk in the interrupt handler and I see it activated 
During the firmware fetch and when I perform the "iwlista wlan0 scan". I kept the IRQ association to IRQ_TYPE_EDGE_RISING as your source code was in 2.6.37 kernel.
Any other idea about why the scan command it's not properly working ?

Regards

Alberto
