Hi All,

Just FIY since nothing relevant was found at google.

I was upgrading my CURRENT system to rev r268233 from a one-or-two
weeks old system. The system was created years ago and had rather
old zfsboot code. So, after upgrading and rebooting I got the error
right after BIOS POST...:
-----
"ZFS: unsupported compression algorithm 15"
-----

... and instant reboot.

OK, I've booted from a USB stick, run the command (the system in
question is at /dev/ada1 and the system at USB stick is rather new
CURRENT also):
-----
# gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1
-----

Now my system is fine again:
-----
% uname -a

FreeBSD bsam.int.wart.ru 11.0-CURRENT FreeBSD 11.0-CURRENT #73 r268233:
Fri Jul  4 06:41:28 SAMT 2014
bsam_at_bsam.int.wart.ru:/usr/obj/usr/src/sys/BB64X  amd64
