I know this doesn't help much, but I've been running 20 days without issues, having both 100mbit and gigabit devices.
Well. What patches applied?
I see high amounts of interrupt errors when checking /proc/interrupts. Most likely from the wifi chips. Is this of any relevance? On my r7800 I don't have any errors ...
I tried several times compile and flash kernel 5.4 firmware for rampis MT7621, network and switcher never work. Ping to router always timeout. Now still keep stay on 19.07-SNAPSHOT branch with kernel 4.14.176.
When flashing a 5.4 build, did you make sure you did NOT keep settings?
Network and switch always not working no mater keep settings or reset to factory settings.
Thanks, it does help me a lot, as I need to stay on 4.14 / 19.07.x base, and these patches seem to stabilize the router.
I have a specific issues that just surfaced when switching from a Netgear CM600 to a CM1000 cable modem. The router just constantly reboots on the CM1000, so I suspect it is using Pause frames and causes the router to crash and reboot. So the FC off patch would likely help, right?
Anyone know how to turn of Flow control on port 5 on an existing deployment?
I can't deploy a new build until several weeks from now, but would love to be able to run a cli command or edit a setting to turn off FC so that unit can run with the CM1000.
I have 16+ days of uptime on 5.4.35, and have no kernel errors whatsoever. (Dlink 860L). And one leg of the router still has flow control enabled (all gigabit).
After 20 days of error-free uptime, today I upgraded to 5.4.42, lets see if it continues to be stable.
Any news on HW offload?

I Think, need activate second RGMII link, like Padavan software, and no need some workaround.
Ok, no 1 Gbps light, but no errors.
Or you can give the latest maser a try. I am running on it for quite some time, have no errors whatsoever.
Activating the second RGMII link can cause issues, if I remember correctly this is explained this in the v5.4 PR by one of the developers. Take a look before you proceed.
Well, in spite of 19.07.3 having the flow-control fix discussed in this thread, it is still susceptible to the timeout crash.
Is there any hope this will get addressed in 19.07.4?
I can't move to master, and can't wait for a 20.x, whenever that might come.

The flow control commit (https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=498f1f4f5df2d077ba524f5735906bb52c12d580) was committed after 19.07.3 got tagged. So 19.07.3 does NOT include that commit. You can get it by installing a 19.07 snapshot if you want (do not confuse this with a master branch snapshot). Download link here: https://downloads.openwrt.org/releases/19.07-SNAPSHOT/
Ah, thanks for pointing that out. Will see if I can recompile with that.
I signed up only to say that this is what fixed my issues with three R6350's using the MT7615 for me. I dont have a build machine but half the wifi drops and low Wireless speeds for me were fixed by using the MT7621 build from this tree.

Tried the snapshot out on my netgear r6220 (MediaTek MT7621 ver:1 eco:3) and it seems the timeout still happened. I couldn't gain any access to the router as well, I was forced to remove the power to make it work again. I'll see if next time I can gain access to the log and confirm if the driver does indeed behave the same.
Can confirm the same on my RT-AC57U, which automatically rebooted unfortunately. Strangely, my DIR-860L at home running 19.07.1 has crossed over the 100 days uptime now with no real issues to speak of.
It seems to be happening every hour now for me. Any idea how to extract kernel logging after power cycling from a previous boot? I can't access the device through luci/ssh.
Try to disable packet steering (RPS) that was enabled by default a few days ago.
I am using RPS for 2 months now on a DIR-860L and it does not create any issue, at least not on my end (with kernel 5.4).
