CCR1036 stuck after fcs error on link

RouterOS General
1

Just bought CCR1036-12G-4S. Moved from RB2011. Configuration the same.

I got trouble with this router. It stops forward traffic, and becomes completely inaccessible. ping to this router also said “Destination Host Unreachable”. Only reboot helps. The main thing that router after reboot works fine, without messages about fcs errors, but after 5-15 minutes this message appears and router goes down. I tried to set port speed manually, but no luck.
This is first time with all mikrotik devices I want to destroy it. Is this a hardware bug and I should replace device or maybe exist some workaround?

Logs looks like following and repeats every 30 seconds:

try to disable this, I think it is: ethernet interface set ether1 tx-flow-control = no
ethernet interface set etherx rx-flow-control = no

or

changed the TX/RX Flow Contros on Interface to “auto”.
