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".

ec2 image not starting after dist-upgrade
Hi! Im running testing/sid. After last dist-upgrade image refuses to start. I pasted the output from aws at the end of the mail I think this is the key -->"ERROR Invalid kernel: xc_dom_probe_bzimage_kernel: unknown compression format". I read somewhere about grub having problems with xz images, but not sure how to fix it. So far I tried to change /etc/default/grub from GRUB_DEFAULT=0 to 2 and run grub-update with the disk attached to another instance, to try to boot and older working kernel, but now the instance start and stops without showing any errors my google fu does not show anything and i dont really know much about the kernel to mess with it and i would probably only make it worse on my own.
