This bug is awaiting verification that the linux- aws-6.2/6.2.0-1014.14~22.04.1 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-jammy-linux- aws-6.2' to 'verification-done-jammy-linux-aws-6.2'. If the problem still exists, change the tag 'verification-needed-jammy-linux-aws-6.2' to 'verification-failed-jammy-linux-aws-6.2'.
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] There's a part of system firmware, IOM, need the driver to disconnect all TBT/Type-C phy to let dGPU function normally. [Test] With the fix applied, the dGPU continues to work after replugging video cable many times. [Where problems could occur] The fix is composed of several overhaul, so it's likely to regression i915 GFX driver. To limit the impact, only target OEM kernel for now.
