Subject: 2.6.39.2 BUG: unable to handle kernel NULL pointer dereference
I'm trying to boot with 2.6.39.2 but the process stops somewhere in
network stack, with a BUG: report.
I've been able to capture the kernel messages usign netconsole, so be
patient with poor alignment :)
Please note that at this moment I'm not subscribed to LKML, so please
keep me in CC if any answer is required. Below you can find the
netconsole trace and .config file.
Thanks for the attention.
