This bug is awaiting verification that the linux/5.15.0-74.81 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.

How reproducible: Steps to Reproduce: 1. On the Dell system enable "Performance Per Watt (DAPC)" from BIOS. 2. Install Ubuntu-22.04 3. Boot into OS 4. Check the bootup time Expected results: OS should boot normally and need to consume less bootup time [Fix] 13fdbc8b8da6 cpufreq: ACPI: Defer setting boost MSRs [Test Plan] 1. Set system profile as "Performance Per Watt (DAPC)" from BIOS setting 2. Install Ubuntu-22.04 3. Boot into OS 4. Check the bootup time [Where problems could occur] Regression risk: low to medium.
