Ok. Failed to mention one important step -> alt-sysrq-7. With alt-sysrq-{1...6} it does not hang.
1. boot the system and login as root 2. load netconsole (insmod netconole.ko netconsole=blah... blah...) 3. issue alt-sysrq-7 4. unplug the cable (link goes down) 5. system is frozen until forced to reboot

Did you try reverting that?
Yes, just tested it. Sorry. It doesn't change anything.
