Thanks! It's better that if you can capture these info via netconsole
or something like that, so that you copy and paste them into email.

Hmm, it seems that a null pointer deref happened in
net/ipv4/devinet.c::inetdev_init(), so Cc'ing netdev guys....

Could you please run the command:

addr2line -e your_2.6.32.8_vmlinux 0xc11fea28

to check in which line we dereferenced a null pointer?

Thank you!

Hmm, thanks, we already found the problem, I think the patch here:

http://patchwork.kernel.org/patch/77357/

should be able to fix this problem.

Thanks for reporting!
