Running on a new Rb711-5Hn-MMCX

5.0RC1 on both AP and client

I have ether1 and wlan1 bridged, one host connected to ether1 (tried a PC and a router - same results)
The host pops up in the bridge hosts list for a second and then goes away. Randomly appears again, then goes away. Device behind ether1 cannot pass traffic.

Downgrade to 4.11 - all works normally.

Anyone else seen this? I MAY have seen this on a 411 board as well today, but was unable to test enough to narrow the problem down.

-- Slightly off-topic: Will failed wireless connections from non-nv2 clients show up in the log if trying to connect to an nv2 AP?

I've noticed this bug does not seem to appear on 411 boards, just 711.
