I have tried the same compilation and exactly the same configuration (from a backup). I have removed the new Switch, leaving EVERYTHING exactly as it was 3 months ago working. It keeps getting hanging. I completely deny. I'm not going to spend another second of my time on this. I'm going to sell the router and will never buy something with a "ShitTek" chip again.
Please try 19.07.5
I've tried it, clean install. Same behavior.
Only left to try EdgeOS from Ubiquiti to rule out a hardware problem.
I have temporarily configured syslog in flash, to see what happens when the Switch hangs. And this is what I found after manual reboot.

I thought it was not giving any transmit timed out error while working, only gives it when it freezes and couldn't see the syslog in ram after a reboot. I had never seen the error of the first line where a packet is received from the router itself (?).
It seems that transmit timed out repeats every 10 seconds until i reboot the router.
I have left everything exactly as it was a few months ago, when I had no reboots or crashes. But I get nothing. Also i tried patch from Mushoz (Mt7621 / mt7530 programming: Disabling Flow Control on all ports) to disable pause frames advertisement but without positive result.
I can recreate this situation quickly, just using iperf between LAN - WAN (or two routing interfaces) with no more than 20 threads is enough ...
The truth is that I do not know if the problem has always been there. With a "normal" use of the connection does not happen (even with P2P or large downloads). I can only crash it with iperf.
Hi apocalypse,
There have been cases of dodgy lan cables or mixed match duplex upstream causing this issue. What is this connected to? upstream connection?
You can do a 'cat /proc/interrupts' -- share the output
Also do a 'swconfig dev switch0 show' - share output
Look for RX and TX Drops and pauses, this indicates connectivity issues

You can see the ERR stats are low for me, because im using a new NAPI polling function for the wifi chips. And spreading the interrupts across the cores, as per the manufacturer script does.
What router are you using?
Iperf will stress the switch stack, and show possible issues.
Router is ER-X. Connection is FTTH connected to port eth0 (WAN) and managable Switch in eth1 (LAN1).
VLAN config very simple, to rule out problems.
WAN port: VLAN 2, untagged
LAN port: VLAN 1, tagged
CPU: VLAN 1 & 2, tagged
All other ports are not members of any VLAN.
I think none of cables are bad. Anyway, I have only tried connecting the ONT and the server with iperf, doing the test to WAN from 4G network in laptop. And the same thing happens. The cables I have tested are pre-fabricated. I have already ruled out all that, the problem is the router hardware or the damn driver of this SoC.
/proc/interrupts show 0 ERR (You can see some post above, a capture where it had 33 days of uptime and without errors).
swconfig show 0 count to all TxDrop, RxDrop, TxCol, TxPause or RxPause of all ports. I can't tell at kernel crash time if those values have increased.
There are many posts and many people with the same problem and nobody comes up with a definitive solution. We only speculate that if it is due to Flow Control, that if it is because of having more than one port in the same VLAN ... patches here and patches there ... but in the end nothing will solve it.
I have switched to snapshot master branch. It seems the problem is over. I've been running iperf tests for an hour or so and it won't hangs or rebooted.
well, this is why I urged upstream to switch to the upstream DSA driver instead of the buggy swconfig driver.
Is my problem same?

It looks like it is. I recommend that you try the latest snapshot. You will need to do a clean install, the network settings are not compatible.
or just delete /etc/config/network.

Yes. The conversion of swconfig to DSA requires it. Backup your wireguard config first.

Thank you.
My plan is this: delete the /etc/config/network file, reboot (will the router set the default configuration?) And connect with a cable and do the settings again?
Yes it will regenerate
Delete /etc/config/network, without reboot upgrade to latest snapshot (keeping settings). And when it has been updated and restarted, the new config will regenerate.
If you restart after delete network file and before upgrade, the config generated will still be incompatible with snapshot. The network/switch driver it's completely different, and ethernet devices has another names.
I already have 19 07 5, need to download sysupgrade again? Or i miss something 
19.07.x is the last stable branch with outdated driver. Snapshot are builds from master branch. This branch includes the new DSA driver. You can download it from here: https://downloads.openwrt.org/snapshots/targets/ramips/mt7621/
CAUTION: These builds do not include luci. You must install it from ssh.
opkg update
opkg install luci

I must be facing the same issue on zbt-wg3526-16M after upgrade from 19.07.3 to 19.07.5: in a few days since upgrade i had 2 hard lock ups that i had to hard reset. Wasn't able to access to get any logs.
I will try to setup an external syslog and wait for another lock up, but looks like i will have to go back to 19.07.3
External syslog does not work. All ports stop working before the log can be sent. You must configure the log in flash memory or view it through serial port.
