I see this behavior frequently. It's pretty easy to get SNMP to fall over on the bonded ZyXEL with snmpwalk. I haven't yet figured out the exact sequence of steps necessary to get snmp to fall over, but it seems like if I do anything besides run snmpwalk as soon as the modem boots, then if I later run an snmpwalk, it will fail.
Here's a relevant syslog from the ZyXEL of the kernel killing off its snmp daemon in response to an snmpwalk:
