CCR1036 and AF24 Ethernet FCS Errors

Hi,

We have quite a few AF24 links that are terminated directly into a CCR1036.
Using routeros 6.7 there are no FCS errors logged, using 6.25 there are.

If we use a different routerboard in place of the CCR running the 6.25 firmware there are no FCS errors logged.

I have reported this issue previously with Microtik and it was resolved - but has come back again.

Please can this be rectified?

Thanks,
