Bug#1011168: linux-image-5.17.0-2-amd64: rebooting KVM guest crashes kernel

[Jon <nuxi@vault24.org>]

I found a matching issue on the Arch Linux forum:

https://bbs.archlinux.org/viewtopic.php?id=276648

Which ultimately links to this discussion on one of the kernel mailing
lists:

https://lore.kernel.org/kvm/YnHALvjWw6E94K53@google.com/
https://lore.kernel.org/kvm/20220504001219.983513-1-seanjc@google.com/

And this commit:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d187ba5312307d51818beafaad87d28a7d939adf

I haven't tested a custom build with the patch applied but I can confirm
that the server that I have crashing is an older box with an Intel Xeon
E5645 CPU that lacks XSAVE.

And now that bug 1010916 has an updated backtrace attached its clear
that it is the same issue as this one.
