Linux 6.10.2 output with iwlwifi firmware crash at the end

I can reliably cause iwlwifi firmware (89.202a2f7b.0) on Linux-6.10.2 (and other kernel versions) to crash on an Intel AX210 (Typhoon Peak 2) Wi-Fi card with the following sequence of commands:

1) xset dpms force off
2) xset dpms force on

The firmware and the wireless stack continue to run after 1) but reliably crash upon subsequent execution of 2). The crash is also reproducible if regular timeouts (instead of xset command) cause DPMS to be activated, but the actual firmware crash is never during DPMS activation and always during the subsequent DPMS deactivation.

I am attaching the full dmesg output from Linux 6.10.2 with the iwlwifi firmware crash dump at the end.

Do you know if this did happen with earlier kernels as well?

And does it still happen with 6.11-rc1?

Crashes the same way with Linux 6.11.0-rc1 (see attached dmesg output).

DB cleanup.
