This bug is awaiting verification that the linux/5.15.0-36.37 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.

After a bisect, I found this commit is causing the real-time kernel build failure: dc66c1b8a2be1 ("x86/pkru: Remove useless include") Commit dc66c1b8a2be1 was added in 5.16-rc1 and not cc'd to stable. It was picked into Jammy to enable AMX support. See bug 1967750. The following commit resolves this regression by fixing up the includes: 35fa745286ac4 ("x86/mm: Include spinlock_t definition in pgtable") Commit 35fa745286ac4 was merged into mainline 5.17-rc1. [Fix] 35fa745286ac4 ("x86/mm: Include spinlock_t definition in pgtable") [Test case] Kernel builds are now working after picking this commit. [Regression potential] Low. The new commit is just including a header file.
