[mythtv-users] Problems with the cx8800 module

[René Gram]

Hi

I've just got a WinFast TV2000 XP Expert card with a CX2388X chip.

I have compilede support for the cx8800 module but here is what I get
when I run modprobe cx8800

As far as I can se from the above the module finds the correct card but
then crashes.
Any ideas why it crashes?

Im running Debian unstable with a 2.6.3 kernel.
I have appiled the patches from http://bytesex.org/patches/.
