Verified this on a Thinkpad X230 with lastest Ubuntu 18.04/Linux Mint 19 kernel and Archlinux (4.17.8-1-ARCH). For me, however, the symtoms are a bit different: After boot and after device being removed, devices are not recognized anymore wehn plugged in. "xhci_hcd :00:14.0: HC died; cleaning up" is in the logs. sudo bash -c 'cd /sys/bus/pci/drivers/xhci_hcd; for d in :??:??.? ; do echo -n "$d" > unbind; echo -n "$d" > bind; done' fixes this - but only once. Kernel parameters 'pci=nomsi iommu=soft' do not fix this (iommu=soft is default anyways). However, "usbcore.autosuspend=-1" does seem to fix the issue.
