Hi all, I just updated my ubuntu to karmic and found with surprise that
with 2.6.31 kernel my device does not work... It seems to be related to
the xc2028 code part since the kernel explosion happens when you try to
tune the device, here it's my dmesg, any idea?

This was actually a regression related to the dib7000 driver and any
tuner that uses request_firmware(). I checked in a fix for one board
that hit it. It was introduced because 2.6.28 started using the first
parameter passed to request_firmware(), and the dib7000 driver was
sending null.
Can you clarify which bridge your device uses.

Oh, you're using the stock 2.6.31 which didn't get my fix yet. Please
try the latest v4l-dvb tree and see if it still happens.

Might this have something to with problems that I am having with the
Dvico dual digital 4 with karmic?
