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/ynhalvjww6e94...@google.com/ https://lore.kernel.org/kvm/20220504001219.983513-1-sea...@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. -- Jon Doge Wrangler X(7): A program for managing terminal windows.
