I am running Linux version 6.2.14 on my board, the driver seems to be initialized properly, but once the system is booted, with an interval that is less than a minute, I get a group of (reason -52) messages:

There was a similar issue mentioned here (https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/#25163497) , but the fix is already in the kernel that I am using right now.
Any ideas, what could be the reason, and how to resolve it?
Tried older firmware version but that didn't help.
Thanks
