The user describes it on the Arch bug as: """ core/linux-firmware-mediatek@20250917-1 causes network to fail startup and dramatically slows down basically every operation in the kernel. symptoms are a pegged kworker thread at 100% cpu util, shutdown being prevented, extremely slow commands like sudo, filesystem access. I suspect a interrupt storm of some sort. """ And another mentions that removing the module w/ modprobe -r mt7921e hangs. thanks, sam
