Since the upgrade to kernel version 6.0.5, my dmesg is overflowing with AER errors like these:

I am currently using the wifi driver from here, which I had to update due to build failing for kernel 6.0.5 (this driver is working despite the flood of errors). The same issue happens with the rtw88_8821ce kernel driver, with the added problem of not being able to connect to my network.
Should I report this as a kernel bug?
