This bug is awaiting verification that the linux/6.8.0-50.51 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux' to 'verification-done-noble-linux'. If the problem still exists, change the tag 'verification-needed-noble- linux' to 'verification-failed-noble-linux'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] The TBT monitor HPD will be triggered during the resume procedure and call the drm_client_modeset_probe() while struct drm_connector connector->dev->master is NULL. It will mess up the pipe topology after resume. AMD submitted a patch to fix this issue. https://lore.kernel.org/all/20240927170103.102180-3-jerry....@amd.com/T/#e868f6b967ec79ae85c5a8a446be9b5d5c97e5427 [Test case] 1. Boot to OS 2. Plug thunderbolt monitor to the system. 3. Enter suspend 4. Press the power button to resume from suspend 5. Should not hang [Where problems could occur] Pretty low chance to introduce any regressions. The patch won't do anything bad to the system while resuming, the probing will be done after resumed.
