FS#2053 - Regular crashes of ath10k-ct driver on ZyXEL NBG6817

Model ZyXEL NBG6817
Architecture ARMv7 Processor rev 0 (v7l)
Firmware Version OpenWrt SNAPSHOT r9010-adc8b374e3 / LuCI Master (git-19.007.66460-4edac36)
Kernel Version 4.14.91
Local Time Thu Jan 10 10:57:42 2019
Uptime 16h 32m 57s
Load Average 0.40, 0.34, 0.18

Sadly there isn’t any simple way to reproduce, but they seem to be happening somewhat regularly. Since I put the device to use, 1 yesterday, 2 today.

The versions of packages in use:

ath10k-firmware-qca9984-ct - 2018-10-10-d366b80d-1
kmod-ath - 4.14.91+4.19.7-1-1
kmod-ath10k-ct - 4.14.91+2018-12-20-118e16da-1

The router (haven't mentioned it above) has been in use since yesterday. We will probably switch to standard (non -ct) firmware and see if it helps.

Can you try again with a more recent version of OpenWrt (master or 19.07.3)? ath10k-ct has seen a lot of improvements ...

Paul commented on 16.10.2020 12:59

I am on 19.07.4 and I cannot go more than a few days without it freezing. Not sure if this is the same bug here as it locks up so I cannot see any logs.

Shane commented on 04.11.2020 07:19

I have run into what appears to be a similar issue with the NBG6817 as well - it seems to have gotten a bit worse since updating to 19.07.4 with the new ath10k firmware (less automatic reboots, more lockups).

SQM QoS is enabled, 3 virtual WiFi networks (primary, guest, open), with VLANs over Ethernet to another access point (an RT-AC68U running FreshTomato).

With UDP syslog messages sent to another machine on my network, I've managed to capture a reboot (better), and a hang (requires manual hard reboot to recover):

If I should file a new issue instead, share more details, etc, just let me know! I cannot yet reliably reproduce this issue, but it seems to happen every 2-14 days.

Paul commented on 11.01.2021 19:49

So I disabled the 5gz radio on my Zyxel Amor Z2 and the crashing has stopped. I am uptime for 10 days which has never happened before. Just putting this out there for anyone else running to this issue. There is clearly an issue with OpenWRT and the 5gz radio on this device.

Shane commented on 11.01.2021 22:03

I am still monitoring the situation, but I have noticed that the crash seemingly occurs slightly less often ever since a relative's Pixel 3a (non-XL, SoC Qualcomm Snapdragon 670) is no longer connecting to this ZyXEL NBG6817. Meanwhile, the second NBG6817 I set up for this relative at a different place has appeared to continue to crash at the same rate.

Unfortunately, this remains non-deterministic (e.g. right now the relative's NBG6817 has 13 days uptime, with only 10 days uptime here) and I don't have a good way to reliably reproduce the issue. I suspect different wireless clients play a major part in how this bug gets triggered.

2.4 GHz and 5 GHz are enabled here, 3 WiFi SSIDs per band (main, guest, openwireless.org), though the relative's NBG6817 only has 2 per band (main, guest).

Paul commented on 06.02.2021 17:13

I'm still crashing on 19.07.6 with my 5gz radio disabled, just seems to be less frequent, but it could just be coincidence. Is anyone trying out the dev snapshot and can say if that solves the issue?

Shane commented on 17.05.2021 07:06

Good news: OpenWRT 21.02-rc1 appears to have possibly addressed the WiFi driver crash for ZyXEL NBG6817! I've gotten around 2 weeks of uptime without the same crash.

Bad news: I haven't managed to test for longer because Linux kernel 5.4 appears to have a new crashing bug related to the CPU governor frequency scaling; I appear to be getting this bug every time I'm backing up in Deja Dup over OpenSSH chroot'd SFTP (frequently alternating between high CPU and low CPU on the router). I'm testing the "performance" governor workaround now and I'll either add to that bug report (if related) or file a new one (if this workaround doesn't work).
