Orbi RBR863 reboots, connection drops after recent firmware releases
The only firmware versions that work with my Orbi are V7.2.6.31_5.0.24 and previous versions. The latest firmware versions result in slow download speeds, random dropouts/disconnects, and reboots. I ...

So v7.2.8.5 FW is causing issues?
What connection is dropping? WiFI Clients or ISP service?
What Brand and model# ISP modem/ONT do you have?
What channels are you using on the RBR?
Distance in between the RBR and RBS?
Size of home in sq feet please.
There is known issues with IPv6 on FW versions past v.31. Was recommended to disable ALL IPv6 protocols on systems running FW versions past v.31.
I have had my 960 series on line with v7.8.2.5 and is stable and solid. However I don't have natvie IPv6 support from the ISP so it's disabled for me.
Something to try on your 860 series with v.5 FW loaded.
My systems are manually loaded, power cycled, factory reset and setup from scratch for a good clean FW update and system setup.

I updated to the latest firmware, then ran a system capture for 1 minute. I am getting kernel errors across WLAN and daemon errors, so it looks like it's kernel panicking, then rebooting.

Is this happening with IPv6 enable or happening with the ONT connected to the RBR?
How are the RBS ethernet connected to the RBR? Directly behind the RBR or is there any LAN switch in between?

IPv6 is disabled as my ISP does not currently support it. This happens regardless of whether it's PPPoE via ONT or DHCP via the ISP-provided router. Both RBS are connected to the RBR with no network switches in between. I have tried with both RBS powered down and nothing else connected, with the same result. System logs show `kernel.err` continuously, then three `deamon.err` before it restarts.

Have you tried the RBS wirelessly connected instead of ethernet?
PM me the debug logs so we can get them to NG for review.
