[linux-dvb] Re: cx22702 problems / new card ? (was Compilation error wit

Hi,

I've unzipped a clean version of linux-2.6.9.tar.bz2
from kernel.org
Then I applied patch-2.6.10-rc1 from kernel.org
Then I applied
http://dl.bytesex.org/patches/2.6.10-rc1-1/All-2.6.10-rc1.diff.gz

The DVB part of my config file now looks like:

This causes a compile error due to a call to
mt352_attach at line 127 of cx88-dvb.c

If I comment out the offending line, I the kernel oops attached below.

I can set CONFIG_VIDEO_CX88_DVB=m and everything boots
OK, and works fine after modprobe cx88-dvb

Hmm, can you post the oops? I'd guess it's an initialization order
issue, but lets see ...
