[Prism54-users] Kernel panic with prism54

[Kasper Fischer]

Hi Markus,

I am using the Netgear WG511 with an older version of prism54. I have
not updated it for a while. I can send this version to you if nobody
else has a fix for this bug. Remeber that the driver is still in
development therefore you might have bad luck and picked up a broken
version .....
