Here we go folks. I hope I got everything right. The only place I have a
doubt is the 0010: part of EIP. I couldn't read what I wrote there.
Looks like it's ip fragment related?

ksymoops 0.7c on i686 2.4.0-test11.  Options used
     -V (default)
     -K (specified)
     -L (specified)
     -o /lib/modules/2.4.0-test12 (specified)
     -m /usr/src/linux/System.map (default)
