This bug is awaiting verification that the linux-gcp- fips/6.8.0-1035.37+fips1 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-gcp-fips' to 'verification-done-noble-linux-gcp-fips'. If the problem still exists, change the tag 'verification-needed-noble-linux-gcp-fips' to 'verification-failed-noble-linux-gcp-fips'.
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] Backport the patches as needed to noble:linux-gcp and later kernels. [Test plan] Compile and boot test. Verification on Google's side is optional as this is a fairly isolated backport. [Where problems could occur] This fix affects TDX guest VMs which call the HLT instruction. An issue with this fix would be visible to the user as unexpected #VEs (virtualization exceptions) or unexpected interrupt behavior in their TDX guest VM.
