Thinkpad X220 - can'b boot from FreeBSD-11.0-RELEASE-amd64-memstick.img

[Anton Yuzhaninov]

Hi All.

I'm trying to install FreeBSD on Lenovo Thnkpad X220, but unfortunately 
it can't boot from USB stick with 
FreeBSD-11.0-RELEASE-amd64-memstick.img (written using dd).

Kernel is started but root fs can't be mounted:

in mount prompt lists da0 and da0p1 but no ufs labels.

ufs:/dev/da0p1 also doesn't work.

I've tried to increase vfs.mountroot.timeout - no changes.

Boot mode is UEFI (and Thinkpad can be booted only in UEFI mode from GPT 
partitions).

Any ideas why root can't be mounted?
