I'm experiencing the exact same thing (with the same hardware). I'm using 2.6.35.4 with compat-wireless-2010-08-21. Running Bjørnar Hansen's test, my system will freeze around 20. Using the version of ath9k that comes with 2.6.35.4 is impossible because the system would freeze on the first "ifconfig wlan0 up". My wireless connection is also a lot less stable compared to how it used to be with a 2.6.32 kernel on Fedora 12 (I'm using Arch now). I'll try to help in whatever way I can, just let me know what you need. nick -- 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
