Just for the record for those that come after me. After some digging
yes, kernel changed from gz to xz at some point between 3.2 and 3.9
Ec2 run in some xen version that have problems with xz kernels. I just
changed GRUB_DEFAULT=2 to 1. This time I checked that was an actual
entry of some old kernel 3.2 in /boot/grub/menu.lst instead of
guessing the entry. And it worked...
Watch out for, i guess, old xen hypervisor, or ec2 when upgrading your
debian virtual boxes!
cheers!
