Hello Steve, Do you notice any decrease in wifi performance when you see these 'failed to send h2c command' messages?
I noticed in your dmesg file you also see 'firmware failed to leave lps state' around the same time you see the h2c message - this led me to this coversation (https://github.com/lwfinger/rtw88/issues/61). Does this issue seem similar to yours? This may mean the issue is related to power saving. If you feel like your issue is similar to this please verify some behavior by following these steps from the thread: Update: the message flood only happens when laptop charger is not connected. 1) I connected the charger. The "firmware failed to leave lps state" message stopped to appear, but "failed to send h2c command" message still continuously flooded my dmesg 2) I put laptop to sleep, then wake up. Message flood stopped. 3) I disconnected the charger, and after few minutes message started to come in again.
