Not sure if anyone did this since Alioth is down but how about:
The kernel image is now compressed using xz compression.
Normally this should be transparent however if you are running
under a virtualisation system, such as Xen, which wants to
decompress the kernel itself then you will need to ensure that
the system is up to date and includes support for such kernels.
See https://wiki.debian.org/Xen#unknown_compression_format for
more information.
Can this be added to the x86 images only?
The wiki link needs to be filled in also. Something like, under the
"common errors" section of wiki.d.o/Xen:
ERROR Invalid kernel: xc_dom_probe_bzimage_kernel: unknown compression
format
xc_dom_bzimageloader.c:394: panic: xc_dom_probe_bzimage_kernel:
unknown compression format
This indicates that your toolstack is not able to cope with the
compression scheme used by the kernel binary. [Link to Bug #
727736]. Most commonly this occurs with newer kernels which use
xz compression when booting on older Xen installations. Debian
switched to xz compression after Wheezy from package version
3.6.8-1~experimental.1 onwards.
Xz is supported by the version of Xen in Debian 7.0 (Wheezy)
onwards. If you are running Debian guests on a non-Debian host
then you will need to consult the non-Debian host's provider.
