--- Comment #11 from Yann Droneaud <yann@droneaud.fr> ---
When testing against upstream Qemu, I've found v6.0.0 reproduces the problem,
and v6.1.0 doesn't !

So maybe it's not a problem in FreeBSD implementation after all.

Doing some bisecting, I've identified a commit in Qemu that seems to fix my
issue:

  commit fea4500841024195ec701713e05b92ebf667f192 (HEAD)

      target/i386: Populate x86_ext_save_areas offsets using cpuid where
possible

      Rather than relying on the X86XSaveArea structure definition,
      determine the offset of XSAVE state areas using CPUID leaf 0xd where
      possible (KVM and HVF).

I can't tell anymore if there's a bug in FreeBSD kernel, so I'm closing the
bug.
