Hi there,
Same boat here: my mini pc powered by an intel N150 includes a realtek 8821ce Wifi controller.
Under Libreelec 12.2.1 after Wifi was activated the PC ended up locking (around a minute maybe).
Loads of errors in dmesg output. Nothing else to do than a hard reboot.
Works fine under nightly build LE 13 of 6th may; dmesg output is significantly different. However kernel modules are the same.
I noticed however a high CPU usage from a (kernel ?) process irq_88.... (around 25%). That seems odd.
