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.
