Thank you for the report, my comments below.

First of all, do not spoil the commit message with unneeded lines of
the traceback. Only ~4-5 is usually more than enough.

Patch is simply wrong. While Oops will be gone, the driver won't work correctly.

I have heard that new firmware is on its way to the customers, but I
have no more information right now.
