Ok, I'll try to get better oopes. However, this is going to be tricky, as the 
machine is remotely administered (via HP iLO) and uses all network interfaces 
(BTW, I'm not even sure to be able to get a network driver related crash using 
netconsole approach). So far, no success in using a different resolution for 
boot console.
Anyway, I'll try to find a way to capture all the messages.

Many thanks for the answer!
