--- Comment #13 from Leo Bicknell <bicknell@ufp.org> ---
Updated to cp /boot/loader.efi /mnt/EFI/BOOT/BOOTx64.EFI.

Test #1:

Drop to loader prompt.  Manually enter set xxx_load="YES" for all of the things
I had removed.  Run copy_staging enable.  Booted multiuser successfully.

Test #2:

Drop to loader prompt.  Manually enter set xxx_load="YES" for all of the things
I had removed.  Booted multiuser successfully.

Test #3:

Add them back in /boot/loader.conf and reboot.  Hangs after pcib6 as the
initial report.

The drivers in question:

#uplcom_load="YES"
#i915kms_load="YES"
#ichsmb_load="YES"
#pchtherm_load="YES"
#acpi_wmi_load="YES"
#ig4_load="YES"
#uhid_load="YES"
#usbhid_load="YES"
#wmt_load="YES"
#ums_load="YES"

Something is making loading them via 'set uplcom_load="YES"' at the loader
prompt different than loading them in /boot/loader.conf; this may also explain
some of the confusing results I got in my earlier testing -- I would have
expected identical behavior.
