This bug is awaiting verification that the linux-oem-5.17/5.17.0-1025.26 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' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.
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.

The kernel message shows "No bus number available for hot-added bridge". The connected devices can't be found. [Fix] Current linux PCI distribute the "spare" resources between hotplug ports on hot-add but have not done that upon the initial scan. The patches make the initial root bus scan path to do the same. The additional patches are just a small cleanups that can be applied separately too. [Test] 1. Power on the machine with Thunderbolt/USB4 devices connected. 2. Check the kernel message to see if "No bus number available for hot-added bridge" shows up or not. 3. Check if the Thunderbolt/USB4 devices works or not. [Where problems could occur] The patches only apply the same procedures on initial root bus scan which was not done. If the BIOS configures the PCI correctly, everything is OK. It only takes effect for the BIOS w/ unconfigured PCIe devices.
