Kernel failures on hap ac^3, wifi-qcom-ac, capsman

I have seven hap ac^3 routers that run few virtual access points that are bridged to their own vlans on ethernet side.
One is capsman master and others are slaves.
I use wifi-qcom-ac drivers.

I see frequent reboots with possible kernel failure messages on logs. Sometimes routers stay up for several days, sometimes just for couple of hours.

Crash usually start with ethernet port flapping up and down every 6-10 seconds for several minutes. Apparently wifi connections stay up but traffic is not forwarded. After 6-15 min the affected router reboots.

Only log entries I see in the capsman master are that the connection to slave is lost and after 6-15 min, the connection is established.

Any ideas how to start resolving this problem? Switch back to old wifi driver?

Switch back to wireless or you can also try to netinstall those devices to latest version. It does clear possible left-overs from previous installations and might be just enough to keep it stable. For now …

Switching to the old Wireless driver seems to help. The system seems to be stable for now.
