I haven't tried looking in logs because the crashes are so severe I
don't think they'd be able to record anything useful.

Can you please get those messages with net console ?

No, I can't get it to work. I found a good guide at
<http://www.novell.com/communities/node/4753/netconsole-howto-send-kernel-boot-messages-over-ethernet>
and adapted it for Debian but absolutely no messages appear. I connected
it via Ethernet to another netbook which runs Ubuntu. On the Debian one
(the one with the problem I want to debug) I added to
/etc/network/interfaces:

auto eth0
iface eth0 inet static
   address 10.0.0.20
   netmask 255.255.255.0

and on Ubuntu:

auto eth0
iface eth0 inet static
   address 10.0.0.10
   netmask 255.255.255.0

On the Debian one I added netconsole to
/etc/modules and created /etc/modprobe.d/netconsole.conf containing:

options netconsole netconsole=4444@10.0.0.20/eth0,6666@10.0.0.10/00:1E:68:DD:DB:40

I used to give
 dmesg -n 8
along  with the above command and I get all the messages in the remote laptop.

On the Ubuntu one I ran:

nc -l -u 6666

I've double-checked the addresses etc and verified that the link is up
and the netconsole module is loaded, but no messages appear.

Can you please try this once again with the above debug level and see
if you get the crash log?

Vivek.
