I should probably plead for the essence of 
<https://cgit.freebsd.org/src/commit/?id=b304cd9789ca7ff3df629af42a976450e8660a11>, 
very recently committed to stable/12, to be committed to releng/13.0 and 
main.

If I understand correctly, the effects of PR 251866 
<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251866> are not 
limited to vmware.

The same symptoms – essentially, unable to boot – are seen with (for 
example) HP ProBook 440 G7.

Thanks
