BUG REPORT:
[1.] I got OOPS messsage and crash ip_queue module
[2.] I using own program (gladiator with libipq ) that use ip_queue kernel module.
After some hours of work my program crash because crash ip_queue and I see OOPS kernel message.
After that i can not rmmod ip_queue and insmod ip_queue. Kernel said module ip_queue is deleted.
[3.] networking/kernel
[4.] Kernel version
root@spider:/usr/src/linux# cat /proc/version
Linux version 2.4.21-brnf (root@spider) (gcc version 3.2.2) #1 Tue Jul 8 20:59:18 EEST 2003
See below about patch.
[5.] root@spider:/home/wireless# ksymoops <oops.txt
ksymoops 2.4.8 on i586 2.4.21-brnf. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21-brnf/ (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.

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
[X.] Other notes, patches, fixes, workarounds:
I patched 2.4.21 kernel with ebtables-brnf_vs_2.4.21.diff (http://ebtables.sourceforge.net/)
I have other server with same patched kernel but there is all right,
I use tunnel interface and send all forward traffic to ip_queue module .
Maybe ip_queue crash when traffic is not from physical device?
modprobe ipip
ip tunnel add netcity mode ipip local 192.168.7.100 remote 192.168.2.100 ttl 64
ip link set netcity up
