           Summary: ipw2200 draws power even when wireless disabled in
                    NetworkManager
           Product: openSUSE 10.3
           Version: Beta 3
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: Mobile Devices
        AssignedTo: behlert@xxxxxxxxxx
        ReportedBy: pbaudis@xxxxxxxxxx

Even if I disable wireless in NetworkManager, my ipw2200 wireless draws power;
my powertop measurements have shown that without ipw2200 module, my notebook
draws 15.3W, with wireless disabled but ipw2200 module 15.8W and with wireless
enabled (and associated) 16.8W. Part of the problem is that apparently the
wireless transmitter doesn't turn off completely (?) and another part is that I
still get a *lot* of interrupts from the card which keep waking up the system
and CPU almost never gets to C3 state (though it's there almost all the time
without the ipw2200 module).

(It would be nice if this would behave saner even with wireless enabled and the
system wouldn't be kept bombared with interrupts all the time even though there
seems to be no heavy network load. CPU likes dozing off in C3.)
