--- Comment #1 from Ruslan Garipov <brigadir15 at gmail.com> ---
After r358989 I unable to boot my FreeBSD 13.0-CURRENT VMware guest
systems anymore.  Even with that ``loader prompt trick''.

I wrote to Toomas Soome, and he said[1] that:

Therefore, currently I have to revert r358989 to be able to boot UEFI
VMware guests on VMware ESXi or Workstation.  But that patch is not
actually the reason for boot failing.
