Hi, I recently got new Lenovo Thinkpad T480s with the ThinkPad Thunderbolt 3 Dock. The USB ports (but probably also audio and ethernet) on the dock always don't work after resume from suspend on up-to-date Fedora 29 with kernel-4.18.9-300.fc29.x86_64. HDMI port in the dock seems works (but with some delay). It doesn't work even with latest available kernel-4.19.0-0.rc5.git0.1.fc30.x86_64 from rawhide. Replugging the dock usually helps to fix that issue. Some probably relevant lines from dmesg after resume: [ 6528.075126] xhci_hcd 0000:0b:00.0: Refused to change power state, currently in D3 [ 6528.075127] xhci_hcd 0000:09:00.0: Refused to change power state, currently in D3 [ 6528.075139] xhci_hcd 0000:0b:00.0: WARN: xHC restore state timeout [ 6528.075140] xhci_hcd 0000:09:00.0: WARN: xHC restore state timeout [ 6528.075140] xhci_hcd 0000:0b:00.0: PCI post-resume error -110!

Not sure what firmware version is in the dock, because I don't know how to check that on Linux. Full dmesg output you can find on the following bug report: https://bugzilla.kernel.org/show_bug.cgi?id=201255 Is there anything else what I can provide?
