Hi, > I recently obtained an rt61pci NIC, and in an attempt to find out > whether my recent hostapd problems were rt2500pci specific (remember > that?) I plugged it into the server. Yeah, I know the issue, I still have it on my todo list but haven't had much time to take a real close look at it. > the interface goes up well, but I get an oops as soon as I run hostapd, > seems something with debugfs. This shows up in dmesg, let me know if you > need any more info. Johannes, this issue might have been introduced in your patch "[PATCH] mac80211: fix key vs. sta locking problems" do you know about this issue?
