Random reboots - 2 MediaTek MT7620A devices - 21.02.1

quirino1977 · November 13, 2021, 8:12pm

I have 2 devices. TPLink Archer C50 v1 and Xiaomi Mini. Both MediaTek MT7620A and were working fine. They were at 21.02 and yesterday i noticed some random reboots. So i decided to upgrade to 21.02.1. Fresh install. Config from scratch. Same behaviour. (OpenWrt 21.02.1 r16325-88151b8303 / LuCI openwrt-21.02 branch git-21.295.67054-13df80d)

After it reboots, i got no log. I took a look on /var/log but no file is there. Did the path changed? How can i track the reboot problem? I forced to write on /var/log but on each reboot all log is gone.

I also have 2 more deviced. Very old, running custom 18.06.8. All of them are DUMB AP. I just use LAN ports. WAN is diconnected.

I tried many resets, changing almost nothing. Only SSID and Wifi Security. Also stopped odhcpd, dnsmasq and firewall and changed Lan IP. Tried to use year 2020 in date, tried to turn off radios (2 and 5 GHz). No luck. Both reboots ramdonly. Sometimes in 2 hours, other, in 2 minutes.

Since both hardwares got the problem, should it be a bug? Log only show messages after reboot, so i cannot find what happens when it reboots.

Looks like sometimes CPU usage is high. But until i realize and try to use TOP, it's normal again.

The most i got today was:

Since i have 2 devices with the same random problem, i thought it could be a bug. At the other side, before upgrading, the devices worked for months with no problem that i could notice until yesterday.

Any tips? How could i track the problem?

Thank's a lot.

I believe /var/log is symlinked to /tmp/var/log so it is still ram filesystem
you can verify this with
ls -lsa /

something you can try is to remove the firmware for the external radio, of course this would cause you to be stuck with 2.4 Ghz probably, but it would verify the real problem if the reboots stop, then you can make a bug report with better information

opkg remove kmod-mt76x2

Thank you.

Yesterday i turned off the 2.4GHz on one TP-Link and 5GHz on the Xiaomi. The TP-Link reboots. The Xiaomi no (20h uptime). I turned 2 GHz off And 5 GHz on @ TP-Link. Uptime: 10h.

This do not make sense since i turned off both radios and they rebooted. Bit i will keep an eye on it. When it reboots, i will try what you suggest.

quirino1977 · November 15, 2021, 8:46pm

After more than a day with no reboot (and 2.4 GHz radios off), i decided to turn it on and both "rebooted" after a while. So i removed the kmod-mt76x2 on the TP-Link.

By the way, i changed the log file path. And now i'm not sure about the reboot. I used to tell it reboos since the uptime start again and there was no log (the devices are not easily visible). But i was looking @ uptime and log and i realize that there is no boot log.

The last logs before uptime start from zero is:

Is there another stuff that could reset the uptime?

Another uptime reset (@ Xiaomi - both radios on, but with low poer (16db) while i was writting. First, the time situation:

Local Time	2021-11-15 17:18:47
Uptime	1h 0m 12s

It means the start was as 16h:18m. There is no log sugesting a reboot ad this time.

I removed the final part of the log (WIFI client connecting - post oversized the limit). But there is these associations only on the end. Maybe it reboot with wring time?

I really don't know what to do. Will look for new devices, but got curious about this problem.

Well. I was looking some logs (and log.old). Something interesting. Looks like it always go back do a specific point (time).

Anyway, this doesn't help a lot. Only know that when it reboots, the clock got wrong.

quirino1977 · November 15, 2021, 11:42pm

The TP-Link, with the kmod-mt76x2 removed, reseted the uptime

Local Time	2021-11-15 20:35:01
Uptime	1h 20m 2s

This means the problem was around 19:15
The log confirm the problem, with no help at all:

The only suggest is that when a client roams from one AP to another, the AP crashes.
I will config each AP with a different SSID and see what happens. If it does not solve the problem, I will downgrade and see what happens.

mpratt14 · November 17, 2021, 8:03pm

I would monitor free memory throughout the day...

quirino1977 · November 18, 2021, 12:53am

I wouldn't expect a lack of memory. One is 64MB and the other 128MB. And both are dumb. No NAT, no WAN port in use. I checked and they are rebooting when nobody is at home. How could the device have no free memory?

But already started monitoring with "top -b > file.txt" Is there a better way to monitor this?

quirino1977 · November 18, 2021, 1:28am

That was fast. Already got a reboot.

quirino1977 · November 20, 2021, 12:25am

I downgraded the TP-Link. One day and no reboot yet.
Some more days with no reboot, i will downgrade the Xiaomi (that rebooted today).

mpratt14 · November 20, 2021, 1:03am

just for the hell of it, try a master snapshot

(note that its possible something doesn't work right, but I think the state of master branch is good right now)

https://firmware-selector.openwrt.org/

quirino1977 · November 20, 2021, 3:51pm

I will wait some more days to be sure the downgrade fixed it.
I can try the snapshot. The goal is to help diagnostic so it could be fixed. But i don't know how to track it. I did what i could and ended up with no ideas...

Ps. it's important to mention that 21.02 also had the same reboot problems. That was why i updated to 20.01.1.

ulmwind · November 21, 2021, 6:48am

OpenWRT works unstable on some devices. You can try Padavan instead.

uniq · November 21, 2021, 11:39am

Hi,
The problem is exactly the same on the router Newifi D2 (Newifi3) MT7621.
On 21.02.0 / 21.02.1 - random reboots. I had to go back to version 19.08.

quirino1977 · November 21, 2021, 9:57pm

Hello @uniq . Welcome. Good to know your first post is to enforce the problem. 3 days with no problem with 19.07.8. I also used 19 for a long time. I hope 21 got fixed soon.

@ulmwind never tried padavan. The previous open wrt worked fine, and it's fine yet after downgrade. Maybe a give a try for padavan in the future. Now I first needed to fast fix the problem.

quirino1977 · December 5, 2021, 3:07pm

After downgrade onde device, the reboots stopped. The other device itr still rebooting, but less frequently, wich made me "tolerate" the reboots and keep the new version until today.

joop · December 25, 2021, 10:51am

I have a TP-Link Archer C2 v1 and experience random reboots with 21.02.1.
So far it seems to stop reboots.

Rolled back to 19.07.8 and noticed a speed bump as well. No 21.02.1 for me, wonder if this should be mentioned on the device wiki as well.

joop · December 25, 2021, 10:55am

@Grzesiek11 Please consider adding a note to the device page. (https://openwrt.org/toh/tp-link/archer_c2_ac750) Thanks!
Something like:

2021-12-25 Currently some users reported issues with TP-Link Archer C2 v1 with the 21.02.1 firmware. These involve infrequent random reboots. It seems that 19.07.8 is stable, if you experience issues with 21.02.1, consider using 19.07.8 as an alternative.

neesonqk · December 25, 2021, 3:35pm

Having the same problem, randomly reboots and no log, my one could work for few days, then randomly you'll see the reboots from the uptime.
