I hope someone from Cox advanced Tech Support sees this! I have a Moto SB6120 in Orange County CA (92606). Last night Cox did some system maintenance (confirmed by L1 Tech Support) and since then my modem's constantly rebooting. I'm on the Ultimate (100D/50U Mbit/sec) tier and it's been working flawlessly since installation two years ago.
It comes up fine, I get 4 Downstream channels and 3 Upstream channels (as usual) and with what are my typical power levels and SNR values:

... but about 15-30 seconds after the modem's fully booted (all lights on solidly), it reboots. Before it reboots everything is perfect, I get my advertised speeds and connectivity is just as it was before last night's maintenance.
The logs say "Cable Modem Reboot due to partial service" and I think they're being triggered by those "MDD Lost" issues going on.
Calling tech support was pretty useless, having me go thru the same reboot/reset stuff I'd already done and they're out of ideas so they think a truck roll is necessary (yet nothing has changed on this end that a roll could fix).
I think they've omitted or mis-configured some parameter somewhere (as a consequence of the maintenance last night?) and the lack of it has my 6120 thinking that it's not fully configured and causing it to reboot.
If a Cox Tech PMs me, I'll give you my MAC address and other IDing information. I have screenshots for the "Logs" (which I just took down 'cause my MAC was in there) "Configuration" and "Addresses" pages, too.
PLEASE HELP!
