Hi,

I've followed (more or less) this thread:

http://daemonforums.org/showthread.php?t=10444

I have two disks nvd0 and nvd1 with three partitions on each: efi, 
freebsd-swap and freebsd-zfs. I've created the ZFS pool and installed 
FreeBSD manually (because on nvd1 I have also a few partitions used by 
Windows). On nvd1p1 I've created the hierarchy of files as outlined in 
the post:

efi/boot/BOOTx64.efi (copied from /boot/boot1.efi
boot/loader.rc (with the content as outlined in the post)

In UEFI boot menu I can see all partitions (Windows, UEFI shell, UEFI 
USB stick for 11.2, and the one I created). Booting from any partition 
works apart from the one I created - when that partition is selected 
UEFI shows a black screen for a second and then goes back to the boot menu.

How can I debug what's wrong?

Thanks
GrzegorzJ
