Hello.
I have a problem with one EX4200-48T. It can't boot JunOS.

And next kernel panic and reboot.
Sometimes it boots, but rarely and in backup JunOS. I've already tried different versions of JunOS - symptoms are similar. I tried to copy backup partition to main - it doesn't work.
Is there any ways of resolving that?
