Hi again,
d6236f6d1d885aa19d1cd7317346fe795227a3cc is the first bad commit
commit d6236f6d1d885aa19d1cd7317346fe795227a3cc

xhci: Fix runtime suspended xhci from blocking system suspend.
I confirmed that reverting this commit on top of v3.16 indeed fixes the
issue.
I just tested the v4.1-rc2 kernel to confirm that the issue is still
present. Reverting above commit again fixed the issue.
Please let me know if there is any other information you need from me.
Can you try with auto-pm disabled for PCI xHCI host?
# echo 'on' | tee /sys/bus/pci/devices/*/power/control
Thanks,

Kind regards,
Ralf
