ArcherA7v5 randomly reboots

Installing and Using OpenWrt
1

Hi

I installed OpenWrt 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-22.083.69138-0a0ce2a on the TP-Link ArcherA7v5. I use Openvpn and Vpn Policy routing for one client.
All works fine for several hours when the system seems to reboot,see my kernel log.
Could this be thermal related ?

Suggestions and comment appreciated.

Grtz.

@aparcar may be able to suggest the status of this well documented error.

Thanks for pointing my to that issue @Bill.

For what i read my best/only option is to try the non CT firmware or am i missing something ?

Grtz.

That is at least worth trying.

Hi,

for the record, changed to the non CT firmware (ath10k-firmware-qca988x 20211216-1) and the system is stable for almost 3 days now.
