Public bug reported:
I have a HP Pavilion dv9000 series laptop (dv9645ed) and i have the
following issue:
When I start the laptop, the b43 wireless card works fine, it connects
to the networks and I have internet.
But when I take out the power cord, i.e. I move to another room with my laptop,
the wifi card stops working.
The led starts flashing blue and orange very quickly and my messages log file
starts filling up with the following messages (note this is 100% repeatable for
me):
