gptzfsboot failed

I recently had a similar issue on FreeBSD 10.2-STABLE #3 r290929.  I have included a pic.

The pool also has a log and cache device along with a mirror vdev.  

I worked around the issue by force importing elsewhere.  It now boots correctly in it's original configuration and a scrub revealed no issues.

No updates had been done recently prior to this issue, in fact I was testing out some values in /boot/loader.conf and had just completed a reboot like 5 minutes before the failed.  The values I added to loader.conf were bogus and are still there so I have no idea what could have caused this.

Similar issue here too. Clean load of 9.x/10.x/11-CURRENT on new ASUS MB with default factory settings boots fine on ufs, but get btx halted with root on zfs. After tweaking some BIOS settings, 10.2-RELEASE and 11-CURRENT (20151130) both successfully boot with zfs on root. After updating 10.2-RELEASE to 10.2-p7 and rebooting we are back to btx halted again and no amount of BIOS tweaking seems to help. Not sure if this is relevant but using an Avago/LSI HBA with 7x2TB drives and RAIDZ3.

amvandemore@gmail.com, can you elaborate on what you mean by "force importing elsewhere" that seems to have fixed the issue for you?
