If you are seeing a problem like this one it may be that you are servicing one packet per interrupt. Then eventually multiple packets come in quick and are received but only 1 interrupt is generated. You need to make sure you service every available packet when you get the interrupt instead of only one.

And Kieran Mansley replied: > In the past I've seen that when a packet has been buffered but ignored. > Receiving another packet causes an interrupt (or something) that > results in the first packet being noticed, but the second packet is > then buffered and ignored. And so on. Not sure if that's any help to you. Anyone has any idea about this ? I turned all debug warning on but nothing shows up when it slows down.
