So, honestly this is not entirely unexpected -- as a good warning to others, 
don't run this yet on a box you care about having back up straight away.

Can you get into kmdb? There should be an option on the grub menu for ISO/USB 
boot, otherwise if you're netbooting you'll need to change config to add "-kd" 
into the kernel args. It'd be useful to know if it even gets to the kmdb prompt 
or not.

Hi Alex,

Not of too a super good start for me :(
I swap in the PI you linked below but the box did not come back.

I did have a serial console open (remotely from work) and the only 
output is:
"Copyright (c) 2"

Nothing else, check the actualy vga console once I get home in like 6 
hours from now.
I'll probaly revert back to the PI I had before this though. It does not 
seem to dump core or reboot. It just seems stuck.

Regards

Jorge
