I patched my 12.0-RELEASE kernel with 343120 and 343166 and now modern Linux
guests boot without needing -w in bhyve (ignore_bad_msr="yes" in vm-bhyve) in
both uniprocessor and multiprocess vCPU guest configs on my platform.
Thanks, Conrad! I'll file a new bug if anything else shows up, and reference
this one if needed.
