Fixed for version 5.8.1 https://github.com/brektrou/rtl8821CU/commit/878da0557a66be55177559f415198c22ec85bc56 https://github.com/brektrou/rtl8821CU/commit/03a238a62a525c9ddf3bb3c0bbe7031be93122b0

@brektrou It is unfortunately still not working on Kernel 4.18.0-240.1.1.el8_3.x86_64, x86_64. I can however confirm, that it works without any errors on 5.9.14-1.el8.elrepo.x86_64, x86_64, RHEL v8.3.

I see similar-looking dmesg output on my MiSTER FPGA system running Linux mst1 4.19.0-socfpga-r1 #9 SMP Tue Sep 8 22:13:28 CST 2020 armv7l GNU/Linux

Built with make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- KSRC=../Linux-Kernel_MiSTer modules

And I made the following changes to the Makefile:

...
CONFIG_MP_VHT_HW_TX_MODE = n
...
EXTRA_CFLAGS += -mfloat-abi=soft

My dmesg output:
