Advanced users • RP5: arch assigned 64-bit MSI address 0xffffffe000 but device only supports 32 bits

I am connecting an M.2 WiFi7 module (ATH12K) to my Rasberry Pi 5 (through the PCIex1 interface). However, I get the following error:

Code:

arch assigned 64-bit MSI address 0xffffffe000 but device only supports 32 bits
I already tried (unsuccessfully) to use the following parameters in the boot config file:

Code:

total_mem=2048dtoverlay=pcie-32bit-dmadtparam=pciex1dtparam=pciex1_gen=3dtoverlay=pcie-32bit-dmapci=assign-bussespci=prefer-prefetchablepci=reallocdtoverlay=pciex1-compat-pi5,no-mip
Is there anyway to (force) enable 32-bit addressing on the PCIe interface of my Raspberry Pi 5?

Thanks!
