Created attachment 304231 [details] fw dump Hello I have a laptop with Intel Wi-Fi 6 AX201. After updating from 6.2 to 6.3, I'm experiencing wifi crashes, wifi restart when traffic is flowing with Pixel 7 Pro (wifi 6E/802.11ax). Other older wifi devices probably not affected (tried Xiaomi pad with wifi 5/802.11ac). Tested with iperf3 in both directions, rsyncing Pixel photos to laptop. The whole system freezes for seconds, no cursor movements possible at these moments (libinput "Touch jump detected and discarded" in logs indicating this). No problem with 6.2 kernel and the recent 6.4rc1 Bisecting leads to this commit of bumping FW API to 74 9ad1e7e5b0c488e4518edd698238a87ac6a73caa, looking strange to me, but reverting from 74 to 72 in 6.3 looks indeed successful with no crash.
