Instead there's now ath6kl.git which follows wireless-testing.

I guess the debug prints slow down the execution and papers over the bug. At least I can't think of any other explonation right now. Before I'm able to find a hw 2.0 device, can you try to debug this more? When scanning fails can check if ath6kldev_intr_bh_handler() is called or not? When scanning fails it usually happens because irqs are failing. Can you share any details about your setup? From linaro.org I assume you are using an arm board of some sort ;) Kalle -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
