This bug is awaiting verification that the linux-aws/5.15.0-1056.61 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' to 'verification-done-jammy- linux-aws'. If the problem still exists, change the tag 'verification- needed-jammy-linux-aws' to 'verification-failed-jammy-linux-aws'.
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.

We would like to have the patch https://github.com/torvalds/linux/commit/c68cf5285e1896a2b725ec01a1351f08610165b8 backported to Ubuntu 5.15, 5.19 and 6.2 kernels. We saw some of these performance improvements: NGINX 1%, MySQL 2%, PyTorch 2% [Test Plan] AWS tested. [Regression Potential] Arm64 binaries may not work correctly.
