Description

iQQator 2022-10-30 11:00:46 MSK

В системе нет драйвера для MT7921K (но есть драйвер для MT7921Е)
В сети нашел решение проблемы, но хотелось бы что-бы уже сразу работало или было описано официально как решается обходным путем :)

WORKAROUND:

$ cat /etc/modprobe.d/rz608.conf
alias pci:v000014C3d00000608sv*sd*bc*sc*i* mt7921e

$ cat /etc/udev/rules.d/99-rz608.rules
SUBSYSTEM=="drivers", DEVPATH=="/bus/pci/drivers/mt7921e", ATTR{new_id}="14c3 0608"

В текущем основном ядре kernel-image-6.12 драйвер mt7921e знает устройство 14c3:0608 (MT7921K / RZ608): drivers/net/wireless/mediatek/mt76/mt7921/pci.c содержит PCI_DEVICE(PCI_VENDOR_ID_MEDIATEK, 0x0608). Обходные alias/udev-правила больше не нужны; ядро std-def снято.
