So Onion has a solution for this BUG issue.
I entered command line mode from the USB terminal, during bootup I get this message:
Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: 8771d944
I got a replacement Omerga2+ today and it seems to work fine. I'll consider the previous one as a bad device...
Dear @Lazar-Demin please let us know what is the difference between these two Omegas.
