I've got a strange problem with the WLE900VX mPCIe card. When powering on the APU2, everything works as expected, after a reboot, the PCI device simply disappears.
[root@apu2 ~]# lspci |grep Qualcomm
01:00.0 Network controller: Qualcomm Atheros QCA986x/988x 802.11ac Wireless Network Adapter
After a reboot its just not there anymore. echo 1 > /sys/bus/pci/rescan does not help either. The only solution I fugured out is to power-cycle the board, not the best solution.
BIOS is at v4.6.8, Linux Kernel is 4.15.17-300.fc27.x86_64
