Z15 unable to boot up

[LittleS]

HI!
One of my z15s is having trouble to finish booting up. From kernel log everything looks normal, but in the end of upbooting the machine just restarts and doesn´t start hashing. Kernel log loads up fine and last thing it shows is connecting to pool and then it makes automatic reset. HAs anyone had similar behaviour and can share how to approach it? I have tried different firmwares also, but still same thing.

HI, it was a PSU problem. Machine started to work after i changed it.
