I am still seeing this issues with 4.13.0-16. Ultimately this problem (at least in my case) seems to be a PCI express power management issue (see https://www.spinics.net/lists/linux-pci/msg64778.html).

The following workarounds solve the problem on my system:
 a) remove the PCI express card from the system, or
 b) disable the PCI express power management in the Lenovo X220i's BIOS

Another option is to use a kernel that reverts commit 8466489ef5ba48272ba4fa4ea9f8f403306de4c7, although the correct solution would be to investigate and fix the power management issues which trigger this problem.
