Well we've seen at one report that it helps, on x86. And the alignment thing is definitely a bug, so fixing it had to help somewhere. But yes, it looks like there's a different bug leading to the same symptoms elsewhere... Here's a thought: iwl_rx_queue_update_write_ptr doesn't synchronise the pointer rxq->bd memory to the device. So if you have a platform that's not cache coherent for IO devices (mine is) that might be a problem. johannes
