I could spend some time on this issue a week later.
I'd like to check whether there is any bugs in the driver itself.
Otherwise, blacklist this specific device for LPM.
Thanks,
Baolu

Just so that it doesn't get lost: I've reported issues with this specific
device and LPM not too long ago. It's entirely possible that the device
somehow is broken, although it works in Windows 7/8/10 and OS X, from what I
know, and at least Windows 10 uses USB3 LPM.
Perhaps figuring out what's wrong with the ping timeouts would also fix this
issue? I'm afraid I don't have any fancy USB analyzer equipment to debug
with, though.
In any case, I'll reiterate my request to turn off LPM for a specific device,
no matter whose fault these specific issues are. :-)
Is there anything else I can do to help fixing these issues? (U1/U2 timeouts
causing disconnects, and xHCI bandwidth estimation being off.) I've been
running with CONFIG_PM=n for a while now, but it is obviously not a good
place to be for a laptop.
