Hi all!.
Today i brought a usb wifi dongle (Linksys WUSB54GC) and test it with
yesterdays releng_7 with a plain generic kernel.
It is configured with wpa_supplicant [0].
When i generate some traffic on it, i get panics [1].
Does anyboady else has problems with it?
How can i go further and collect more info to help hunting the problem?
Thanks!
