6.3.3 | crash n/a
6.3.5 | crash n/a
git | ok ok
(git ~ commit ae8373a5add4ea39f032563cf12a02946d1e3546)
(n/a ~ the driver does not support the firmware, i.e. IWL_22000_UCODE_API_MAX is too low)

But every time it is detected as an AX101. I am more concerned about the misdetection.
Who is mistaken? lspci or iwlwifi? What are the potential consequences?
