| |
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.
Thanks.

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.
