Hi,experts 

we use wifi driver cypress-fmac-v5.4.18-2021_0527.zip for AW-NM372SM(chipset is CYW43438) . This wifi driver downloaded form https://www.cypress.com/documentation/software-and-drivers-archive/wifi-bt-linux-archive.

Our linux version is v3.10.108.

we encountered an uncommon WiFi driver oops,as below:

Hello, GauravS

This Oops only happen once. And we can't reproduce  again.

Before trying the latest FMAC release, we need to find a way to reproduce stably.

 

Also you can deep search this Oops for us.

Hi @mgkiller ,

Were you able to reproduce it again?

If yes can you tell me about the host device you are using when this happend?

If the driver is causing this then we need to find a way to reproduce it stably.

Thanks
