Package: linux-image-amd64 Version: 6.12.6-1 Severity: important
Dear Maintainer, it seems that with Kernel 6.12, Debian opts to employ xz compression for the Kernel (CONFIG_KERNEL_XZ=y). While in general this is a nice to have, on a Xen VM - at least with pygrub as bootloader - this is a big issue. pygrub doesn't seem to be able to boot such a Kernel. Not sure if pygrub can easily be patched to support xz compression, but it may be preferable to refrain to use that option until this situation is solved
