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! -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
