Well, this is the USB-C/DP port, next to the power supply on my ThinkPad X1
Carbon Gen5.

When I remove cable from that port I have these messages:
Feb 29 07:43:46 x1c kernel: uhub_reattach_port: giving up port 1 reset - device
vanished: change 0xfb status 0x7fb
Feb 29 07:43:47 x1c kernel: uhub_reattach_port: giving up port 2 reset - device
vanished: change 0xfb status 0x7fb
Feb 29 07:43:47 x1c kernel: uhub_reattach_port: giving up port 3 reset - device
vanished: change 0xfb status 0x7fb
Feb 29 07:43:48 x1c kernel: uhub_reattach_port: giving up port 4 reset - device
vanished: change 0xfb status 0x7fb
Feb 29 07:43:50 x1c kernel: uhub_reattach_port: giving up port 1 reset - device
vanished: change 0xfb status 0x7fb

When I return the cable back into the port I saw reported messages, however
that's been fixed (no more DRM-specific messages in /var/log/messages) by
rebuilding graphics/drm-510-kmod.
