Hi,
I've been seeing variants of this when I plug/unplug my ThinkPad T460
from the docking station:
usb 2-4: USB disconnect, device number 30
usb 2-4.1: USB disconnect, device number 31
thinkpad_acpi: undocked from hotplug port replicator
thinkpad_acpi: EC reports that Thermal Table has changed
usb 1-4: USB disconnect, device number 61
usb 1-4.1: USB disconnect, device number 63
usb 1-4.4: USB disconnect, device number 62
=============================================================================

I don't have the source/config for this kernel anymore, sorry. Will
probably try a newer kernel at some point to see if it's still
present, it might already be fixed. I just wanted to send a report
just in case it has enough info for somebody to spot what went wrong
without too much effort.
See attachment for fuller log + timestamps. The tainted bits are from
earlier reports of the same type.
