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：
