Note that my report is about kernel 5.2.9.
(In reply to Laurent Bonnaud from comment #4) > > Can you try to upgrade to v5.1.20 or higher? > > Note that my report is about kernel 5.2.9. Ah, sorry, somehow I missed that (or confused with another bug). We'll take a look into this. Same WARNING on 5.2.14 (Fedora 30). Happens sometimes after `rfkill block wlan`.

Still reproducible on Fedora 34 kernel 5.13.10-200.fc34.x86_64. I haven't paid much attention to it before, but my machine has two rfkill switches for wlan.

Adding the correct assignee to Cc: as I'm unable to edit the Assignee field. I just reproduced it today with Linux 5.13.12-1~exp1 (Debian sid/unstable), and *firmware-iwlwifi* 20210818-1. With Linux 5.15.1 I got the trace below, which looks different, but is probably related.
