2.5.51 bttv oops.

I added the 20_tda9887-2.5.50.diff patch to be able to compile it.
Then when I boot it tries to modprobe bttv automatically, it zombies, I press alt+sysrq+k and I get the oops.
For some reason I have no /proc/ksyms in 2.5.51, so I don't know if this is useful at all.


lsmod output :
bttv 78516 0
video_buf 10324 1 bttv [permanent]
i2c_algo_bit 7462 2 bttv [unsafe]
i2c_core 15345 2 bttv i2c_algo_bit
v4l2_common 2656 1 bttv [permanent]
videodev 3455 1 bttv
emu10k1 49952 0
soundcore 3926 2 bttv emu10k1
ac97_codec 9704 1 emu10k1 [permanent]

ksymoops :
ksymoops 2.4.8 on i586 2.5.51. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.5.51/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
