Hi People,
I was wondering if anyone could point me in the right direction / debug what this CPU trace in dmesg is relating to. I believe it may be do to with wireless as 802.11 is referenced in the snippet. This message keeps repeating in the logs periodically.
I am running an x64 version of Openwrt on a Celeron J4125 (micro pc), which makes a very capable cheap, fast and compact router with USB3 etc.
Version: OpenWrt 21.02.0, r16279-5cc0535800
