And even if it works, the card would fail after reboot. Even more, sometimes it would vanished from PCI bus. There's a race between mwifiex_pcie and mwifiex_usb which causes this issue. Currently as a workaround we can blacklist mwifiex_usb. Marvell is still working on a solution. PCI ID: 02:00.0 Ethernet controller [0200]: Marvell Technology Group Ltd.
