Problems with v5.0

I have 2 routers with ROS v5.0rc5 on new Intel server chasis. I can’t use ROS V4.16 because it don’t support my hardware. And have the folowing problems.

1). Each time when i connect to router with winbox, it forgot to show “Add Uptime, Add Memory, Add CPU” bars. And after some time, hour or less forgot password. And i must to connect without password and set it again.

2). On second one, no problems with passwords and bars. But after 8 days of uptime i got today 4 bilions errors on ethernet interfaces.
All errors are on Intel 82576 cards.
No errors on Intel 82574L card.
But bonding is configured only on 82576 cards, so problem maybe with driver, or with bonding.
Also after this bug, i have high CPU usage by ethernet. With no traffic.

No ideas? Can it be bonding issue? Somebody use bonding on v5.0?

My configuration:
Mode: 802.3ad
Transmit Hash Policy: layer2 and 3
