I didn't test this before for I have no wireless AP. perhaps I should
buy one this weekend ;-)
I'm not sure if I need to add Gdium specific support for rt61pci, I
will check the opensde git repo.

I got this error too and found it was not urgent, so no log needed, I
will check it. thanks all the same.

Do you mean CRTL+R? Seems I got similar problem when I was using the
gnome terminal, when I issued something, it just hung and only
returned after several seconds. I used the fbdev X driver.

BTW, which X driver are you using? fbdev or siliconmotion?
