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.
