Hello,

We are experiencing kernel crash when we are stress testing WiFi functionality over SDIO interface.
please see attachment for kernel dump (near end of log)

Looking at your log, I see you use an rtl8822 Wifi device, which is
not supported in the mainline kernel.

I assume you use an out-of-tree driver, right?

When using out-of-tree drivers, it is common to see the driver work on
a specific kernel version and then it breaks on a kernel update.

I suggest you consider using a well-supported Wifi chip instead.
