Hi all! I'm trying to find a solution to a firmware crash with atheros firmware.

I've googled a lot about this chipset QCA9377 and it seems that it could be a broken hardware or a firmware bug. Randomly, the firmware is crashing and based on other searches, it seems that is happening when the wifi changes the frequency. This is the last log:
