Intel AX210 "failed to evaluate _DSM" messages

Hi 

I am trying to evaluate Intel AX210 on Nvidia's Jetson AGX Xavier platform.
My OS is Ubuntu 20.04 (Linux kernel version  5.10.104).
When I change the WIFI status from off to on, I always get following failed messages:

[ 117.271272] iwlwifi 0003:01:00.0: iwl_mvm_power_update_device Sending device power command with flags = 0x1

Although the WIFI  can work there, I still want to know what these failed messages means?
Is there any side effect there? How can I avoid failed messages?

These are the result of bugs in the BIOS' ACPI tables. I would ask NVIDIA about them. AFAIK, they do not have anything to do with the AX210.

Hope this helps,

Seems NVidia enable CONFIG_ACPI option but doesn’t implement the APCI table in UEFI.
When CONFIG_ACPI is enabled, Intel AX210' driver will try to call the DSM function in ACPI table.
Thus the error message appears because of no ACPI table in UEFI.

 

I undef CONFIG_ACPI in the Intel AX210 driver source as a workaround.
So the message is gone.Provide the link as  same topic's discussion in Nvidia forum.
