[linux-dvb] kernel 2.6.9 cx8800 oops with All-patch

[Torgeir Veimo <torgeir@pobox.com>]

kernel 2.6.9 + All-2.6.9-rc4.diff.gz gives me an oops when loading the
cx8800 module.

Then I tried building video4linux-20041025-115100 which works ok, but
the cx88_dvb isn't build by default. If I manually enable it in the
makefile I get;

  CC [M]  /usr/local/src/video4linux/video-buf-dvb.o

make[2]: *** [/usr/local/src/video4linux/video-buf-dvb.o] Error 1

Is the video4linux snapshot and the All-patch mutually exclusive? Do I
need to dvb-kernel cvs drivers in addition, possibly the refactored
branch?
