releng_7: rum0 USB Wifi problem

[Phillip N.]

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!
