AX211 Microcode SW Error Detected Ubuntu 22

rensb — Thu, 16 Jan 2025 19:34:26 GMT

Hello,

I'm using a MAG B760M MORTAR WIFI II which uses an AX211 chipset on Ubuntu 22 on the latest driver. Periodically I get a Microcode SW Error a few times a day on certain machines. Is there a fix for this somewhere?

For background, this is causing a brief pause in my application while the driver is reload. I'm running a timing critical application, so any even temporary pause is causing issues for my application.

Thanks!

Hello rensb,

Please share the information below for me to have a better approach with this issue.

1. Is this issue present from the start?

2. Did you make any recent changes to the system?

3. Is this the original adapter that came pre-installed in your system, or have you changed/installed a new adapter recently?

Please also generate SSU report for me to check your system configuration.

I hope to hear from you soon!

Best regards,

Hi Jed,

Thanks for the response! Attached the result of the scan. This is the different machine that the above log, but it exhibits the same microcode error.

1. The issue presents itself after its been run for a bit, particularly under load, but intermittently maybe once every few hours.

2. No changes when issue was present. After the issue came up, we experimented with trying the older drivers, but the same issue occurred. Curren using /lib/firmware/iwlwifi-so-a0-gf-a0-72.ucode instead of the current 86. We also tried separate config changes, including `disable_11ax=1` and other powersave features.

3. Yes, this is the preinstalled wifi module that comes with the msi motherboard

Thanks!

Hi rensb,

I'm following up on the investigation. Please share the output of the following as I need them to check this further.

1. $ hostnamectl

2. # lspci

3. # modinfo iwlwifi

4. # lsmod | grep iwlwifi

5. # dmesg | grep “no suitable firmware found!”

I hope to hear from you soon.
