1 year ago Previously it occurred twice, within 30 minutes of the boot, the third time it worked for 3+ weeks. Probably it depends on your DAWN setup and the distance from the APs. When it happened last time, 2 of my three devices were on my desk (because I was configuring them), and I suspected it happened because my laptop was bouncing back and forth between them. Unfortunately, I don't have the logs from the last time, but I can remember that there was a device "kick" back then seconds before the issue, and I can see it now too. I am suspecting some problem there when a device gets kicked off the network due to low transmit rates.

I'm seeing the following timeouts on a mt7621 board with mt7915e wifi:
Once those messages show up, wifi is unusable. A reboot is necessary to fix it.
The board is running openwrt 21.02 with the mt76 from c67df0d3130a51d79b558f0329c2ca289c73b16e and with the latest mt76 master (minus multi-bss and WED, plus "mt76: lock mt76_queue before access").
The issue only reproduces with lots (40+) of connected active clients sometimes only after 40 hour and later after boot. Unfortunately, I can also not directly reproduce it locally myself. I only have reports from multiple deployed accesspoints.
It appears as if the mcu is locked up or at least communication with the mcu is no longer possible. SO it appears to be either a problem with the firmware or a problem with the communication between driver and firmware. Any ideas or suggestions further debug or fix the problem would be appreciated.
