Call for Testing: 12.0-CURRENT amd64 memstick installer boot-testing wanted

Hi,

Could folks please help boot-test the most recent 12.0-CURRENT amd64
memstick images on various hardware?  Note, this is not a request to
install 12.0-CURRENT, only a boot-test with various system knobs
tweaked.

The most recent images are available at:
https://download.freebsd.org/ftp/snapshots/amd64/amd64/ISO-IMAGES/12.0/FreeBSD-12.0-CURRENT-amd64-20180529-r334337-mini-memstick.img

We are interested in testing both UEFI and CSM/BIOS/legacy mode, as we
would like to get this included in the upcoming 11.2-RELEASE if the
change that had been committed addresses several boot issues reported
recently.

Please help test, and report back (both successes and failures).

Thanks,

Glen
