bisecting results in following:
crash behavior happened on this commit with switch fw from 72 to 74:
linux 6.3: 9ad1e7e5b0c488e4518edd698238a87ac6a73caa wifi: iwlwifi:
bump FW API to 74 for AX devices
crash not reproduced after this commit on switch fw from 75 to 77:
linux 6.4: ef3ed33dfc8f0f1c81ca103e6b68b4f77ee0ab65 wifi: iwlwifi:
