Hello @jay_chen,

I hope you are doing well.

Thanks for the logs, I checked them.

It appears that the error is related to the "Microcode SW error detected"

I suggest referring to the solution provided in the below link.

Hello @jay_chen,

I hope you are doing well.

Thanks for providing crash logs.

In order to debug this issue further please provide commands you run.
Moreover, Can you check the same using the latest Linux kernel, If possible?

It is recommended to use the latest kernel as it provides updates drivers as well as firmware to work with.

Thanks & Regards,

hi Sanket Parekh

The system runs normally without any operation, just set wifi roaming.

But the WiFi reception is very poor

There was no similar problem in the company, but the problem appeared more serious at the customer site

A new kernel has been prepared, but no validation tests have been done

Thanks for you help

Hello @jay_chen,

I hope you are doing well.

"A new kernel has been prepared, but no validation tests have been done"
->Okay, Please share the update regarding the same.

Moreover, Please make sure to check that on the channel where the wifi chip is running it is either supported by it or not.
It may be possible that wifi is scanning on the channel it is not supposed to do according to the licensed channel and it may lead to the crash.

What are the channels it is roaming on, Please check.
And in addition to that if the channels are too far to connect with please make sure to check the transmission power from the AP side.

I hope this will help you.

Thanks & Regards,
Sanket Parekh
