Hi junjie_tan,

I am getting the same problem. Have you solved this issue? If yes, could you share the root cause and solution whit me? Thank you!

Kevin

[joanxie]

it seems that you have error on PCIe initiation, did you use QCA6174A PCIE wifi and linux 4.14.98 bsp?

[junjie_tan]

Test procedure: The machine restarts and then insmod wlan.ko has a certain probability of appearing in this failure
