Hello,
I have a problem with the RouterBOARD 912UAG-2HPnD and R11e-5HnD miniPCIexpress card, working together.

There is no way to make them work, all I get is:
system,error,critical router was rebooted without proper shutdown
system,error,critical kernel failure in previous boot

The router is unstable in any power configuration, connected directly on 24V, 1.6A power adapter, and on PoE over 5m SFTP CAT6A cable, etc.
The problem start when the traffic is increased, usually on small download (youtube).
Sometimes just enabling the second wlan reboots the router, all this on simple ap brigde configuration.

I have tried to make it work on four different 912UAG-2HPnD and R11e-5HnD, even with two R11e-5HacD, with no success.
Changing the hardware configuration didn't help.
Also upgrade to newest RouterOS and firmware didn't resolved this issue.

Any help would be appreciated.
Thanks in advance.
