No, not a word. It hung after printing this:

...
DHCPRELEASE ...
send_packet: Network is unreachable
send_packet: please consult README ...
sky2 eth0: disabling interface
~# sky2 eth0: enabling interface

I'm running ifplugd, but this time there was no network cable connected. 
Also ran from virtual console this time, the keyboard locked up like before.

SysRq keys work, so I could do sysrq-s, sysrq-b. Also pressed sysrq-t 
before rebooting.

Any use trying netconsole? Can I run it over the wireless interface?
