Ick, but nice to know, thanks.

Yup, we are a little better with todays rawhide. I can now boot with my
ipw3945 internal wireless network card detected, without an oops. It
won't associate tho, as you mentioned.

I then inserted my zd1211rw_mac80211 usb2 network dongle (which has been
working with 2960) and got the attached oops (again with iwlwifi oddly
enough...) Hard hang, *BOOM*.

Maybe something to do with multiple drivers using mac80211?

Richard.
