Hi!

I'm using lava from debian stretch.

I try flash image by fastboot.

At that step job just stuck and util timeout of 10 minutes.

If run command from terminal  
fastboot -s 261a1c5d flash persist /tmp/persist.ext4 
device is flashed in 3 seconds

It looks like, that LAVA doesnt see my device.

I know, that for fastboot better to work with lxc. I also tried with lxc. And it stuck on the same place.
