Bug Description
On cold boot, the W8897 sometimes won't work. 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. Device [11ab:2b38]
USB ID:
Bus 001 Device 003: ID 1286:2045 Marvell Semiconductor, Inc.
