The "dcd tainted" crashes occur for users that enable pixelserv-tls or Exclude devices from ad-blocking (additional configuration via LAN >> DNS Director in router GUI) in Diversion. These features create an additional Dnsmasq instance that appears to conflict with some of the Trend Micro components.
That's not the problem. The problem is the network interface pixelserv-tls creates, which causes dcd to crash - I was able to recreate the crash just by creating the virtual network interface.
So is that what’s causing the device/computer disconnects I’m experiencing? (And if I’m lucky to have still one device connected I could restart dnsmasq so they can reconnect.)
No. DCD is only tied to the Trend Micro components, it has no impact on connectivity.
In your off-topic opinion…
Correct. I have a very simple default configuration and don't use Diversion or any other scripts.
It not off topic…. Original Problem cited above specified diversion. Just trying to help as I don’t use diversion and do not experience the issue. Seems OBE now anyways given ELCP cited the problem without diversion.
I'm in exactly the same situation. Factory Reset, hard/cold reset, Skynet off, different USB, nothing seems to make a difference... except going back to 388.1 or earlier OR turning Diversion off. I am inclined to believe it has to do with the Diversion statistics update at 5:20 and 17:20 ... but that could be human nature: looking for patterns where there aren't any
Can you post the output of:
tc qdisc show root | grep htb
cat /sys/module/tdts_udb/parameters/dev_wan
cat /sys/module/tdts_udb/parameters/qos_wanqdisc htb 1: dev eth0 root refcnt 2 r2q 10 default 0 direct_packets_stat 0 direct_qlen 1000
OK, so Merlin’s fix for one issue has created a new issue.

Since both cases relate to DHCP, I am also getting dnsmasq Tainted errors with dnsmasq V 2.89I'm in exactly the same situation. Factory Reset, hard/cold reset, Skynet off, different USB, nothing seems to make a difference... except going back to 388.1 or earlier OR turning Diversion off.

One can also keep a backup of /jffs on another system, and then port back select files after a factory reset. I installed 'rsync', but an 'scp -r' should work, too. It may also be possible to extract files from a config backup file, but I haven't tried that.

I don't see that one on the supported list for Merlin FW.
