This bug is awaiting verification that the linux-oem-6.0/6.0.0-1006.6 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.

[Fix] Two commits targeting v6.1 to restore the default values. [Test Case] To be verified from ODM side. [Where problems could occur] These two commits restores the default values as expected from USB4 spec at being initialized, so it should be the right behaviour anyway. [Other Info] While this is for AMD Pink Sardine platforms, only oem-6.0 and newer are nominated for fix. ========== original bug description ========== For some reason that PCIe device hotplug is disabled once another OS stack launches prior to Linux CM, which makes some registers not go properly, so correct those registers to meet the default value of the USB4 spec. https://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt.git/commit/?h=fixes&id=31f87f705b3c1635345d8e8a493697099b43e508 https://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt.git/commit/?h=next&id=5d2569cb4a65c373896ec0217febdf88739ed295 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1990922/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
