Do you mean that the "Caps Lock" and "num lock" LEDs are blinking? If so, that
is a kernel panic. You will be able to capture some information about that crash
by switching to the logging console (CTRL-ALT-F10) just after you initiate the
process that causes the crash.

The vendor driver in staging is not really under active development. We are
currently writing a mainline driver that uses mac80211 from the vendor code. Of
course, it is not possible to predict when this driver will be ready.
