Kernel Upgrade Disaster HELP PLEASE!

[Karl]

Hi Kernel Team, I hope I am emailing the correct people.

I Just upgraded Breezy badger kernel as per auto update, and rebooted as 
instructed.

I cannot boot into anything anymore, not even the cd.

I have manged to reboot once out of 12 attempts, it seems the kernel is 
crashing at the point that it is supposed to start loading. The one time 
it did manage to boot,  my NIC was not only non fucrional , but not even 
seen to exist. No idea what else may be no longer functioning.

This is nothing short of disastrous! My LIFE is on this machine.

Evrything worked perfectly prior to upgrading.

Is there any way I can roll back to the previous kernel version? I am 
happy to list any further info, just let me know what you need.

Thanks in advance.

Karl
