This bug is awaiting verification that the linux-gcp- fips/5.15.0-1055.63+fips2 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-gcp-fips' to 'verification-done-jammy-linux-gcp-fips'. If the problem still exists, change the tag 'verification-needed-jammy-linux-gcp-fips' to 'verification-failed-jammy-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.

[Kernel-packages] [Bug 2029405] Re: Change in trace file leads to test timeout in ftrace tests on 5.15 ARM64
This bug is awaiting verification that the linux-intel- iotg/5.15.0-1047.53 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-intel-iotg' to 'verification-done-jammy-linux-intel-iotg'. If the problem still exists, change the tag 'verification-needed-jammy-linux-intel-iotg' to 'verification-failed-jammy-linux-intel-iotg'. 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.
