Hi,

Please check if i210 driver got updated in upstream. This issue seems not from NV driver but device driver has something wrong.

5

Did the WIFI device access an address it shouldn’t have placed?

6

Yes, it is possible.

7

ok Thanks.

8

Thank you for the detailed kernel logs. The SMMU faults, MC errors, and iwlwifi driver warnings suggest a potential device driver compatibility issue with the Intel AX210NGW module on your Orin NX system.

To help narrow down the root cause, could you please provide the following information:

  1. Driver version check: What is the current i210 driver version on your system? You can check this with ethtool -i <interface> or by examining the driver source. Has the i210 driver been updated to the latest upstream version?

  2. Test with updated driver: If you haven’t already, please test with the latest upstream i210 driver and provide the kernel logs from that test run. This will help us determine if the issue is driver-related or firmware-related.

  3. Firmware version: Please confirm the current firmware version for the Intel AX210NGW module and whether you’ve tested with the latest available firmware.

Once we have this information, we can better diagnose whether the issue is related to the WiFi driver, the IOMMU configuration, or the VPR memory constraints on your system.

9
  1. Driver version check:
    ethtool -i wlan0
    driver: iwlwifi
    version: 5.10.120-tegra
    firmware-version: 59.601f3a66.0 ty-a0-gf-a0-59.uc
    expansion-rom-version:
    bus-info: 0001:01:00.0
    supports-statistics: yes
    supports-test: no
    supports-eeprom-access: no
    supports-register-dump: no
    supports-priv-flags: no
    software environment：R35.4.1 The driver that comes with the software package。
  2. Test with updated driver:
    Not using the latest testing
  3. Firmware version:
    Not using the latest testing
    All of them are built-in software packages
10

Thanks for the detailed logs and driver version check. The kernel panics and SMMU/MC errors you’re seeing are consistent with a driver/firmware mismatch or compatibility issue with the Intel AX210NGW on your Orin NX.

To help narrow this down, could you test with the latest upstream iwlwifi driver and firmware?

  1. Update iwlwifi driver: Test with the latest upstream version (newer than 5.10.120-tegra) to see if the SMMU context faults and microcode errors resolve.
  2. Update Intel AX210NGW firmware: Confirm you’re running the latest available firmware for the AX210NGW (newer than 59.601f3a66.0).
  3. Capture new kernel logs: After updating both driver and firmware, reproduce the issue and share the new kernel logs. This will help us see if the errors persist or change.
  4. Report results: Let us know whether the panics stop, change, or remain the same with the updated versions.

Once you have those results, we can determine if this is a known compatibility issue or if further investigation is needed.

ok Thanks
