@gregkh Can I report an issue with 6.12 LTS?
This backport in 6.12: https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-6.12.y&id=805e3ce5e0e32b31dcecc0774c57c17a1f13cef6
Needs this upstream commit as well: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=22cc5ca5de52bbfc36a7d4a55323f91fb4492264
If it is missing and you don't have XEN enabled the build fails: https://gist.github.com/BlackIkeEagle/289bcf2a9ea0e25f0098766538b002da
With this backported patch: https://gitlab.com/herecura/packages/linux-bede-lts/-/blob/0d7e313f13fdae9bde7f79967481f186cc1ba8fd/0003-x86-paravirt-Move-halt-paravirt-calls-under-CONFIG_P.patch it works fine
