It fixes the original implementation of the driver basically. It's just a classic posted-write fix. The write to clear the pending interrupt is asynchronous, so you can get spurrious ones if you return from the handler before it has percolated to the HW. I assume it's just more visible on the 2600 because of the cores are significantly faster but the IO bus is still as dumb. Ryan: You could always add a Fixed-by: tag that specifies the commit that added the initial driver... Cheers, Ben.
