Recently tested, it crashes also -git6 without lockdep compiled. So it seems
actually networking code bug.

I'm still not so sure.

The IP is at ip_route_input but the rest of your backtrace
shows an entirely different code path.

Nothing in the trace matches up, which severely decreases the
usability of the debugging information you've provided.

Enabling CONFIG_FRAME_POINTER tends to make backtraces more reliable.
Making sure that (on 32 bit x86) you use CONFIG_4KSTACKS is enabled also tends
to improve backtrace reliability (less noise from interrupts)

Another good option is to go to http://www.kerneloops.org and try to see if others
saw similar backtraces but with less noise

They are both enabled.
There is nothing similar in kerneloops.

CONFIG_DEBUG_RODATA, 4K stacks, Frame pointers, CONFIG_DEBUG_STACKOVERFLOW -
enabled.

It reboots recently after bringing up networking. Sometimes even not reaching
place where i am loading netconsole.

Always in ip_route_input. This is 2.6.25-rc6-git6, 2 panic's. They are easy
to reproduce, but i cannot do bisect, cause this machine dont have power
switch and in difficult to reach area.
