Hi Stefan,
sorry, I'm not sure how I can get the sc_hw_rev value.
Hopefully this is the requested value:
iwx0: hw rev 0x350, fw ver 67.8f59b80b.0
This is not the "QuZ" (0x354) hardware revision.
However, Linux obviously loads QuZ firmware anyway.
So either there is an override for your device in the iwlwifi dev_info
table, or all Qu devices must be treated QuZ unless overridden.
To proceed I need to know the output of pcidump -v on your system.
We already know the product ID (4df0). The device table also contains
the "subsystem" product ID which matters for the overrides table.
The relevant line from pcidump should look something like:
0x002c: Subsystem Vendor ID: 8086 Product ID: xxxx"
in the "Intel Wi-Fi 6 AX201" section.
Here is the output of pcidump -v
