Hi Stefano, What happens is that the while (newidx != sta->txrate) will continue until the newidx reaches 33. Reason is that BIT(33) is the same as BIT(1) In the rate_supported() function. New sta->txrate will be 33 which is far beyond the valid size (12 in my case). In my system that happens to be a 11g speed :o). I have a trace if you are intresting. Its about 260K data but it show How it happens. I think you need trafik (ping) in order for the relulator to operate.

I couldn't really figure out how to reproduce the bug. > In other words, I do not think a WARN_ON is good solution. Please could you try my 1/2 patch? In the meanwhile, I'll try to use your information for more debugging. -- Ciao Stefano - 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
