[Kernel-packages] [Bug 2025040] Re: increased power usage after upgrade from kinetic to lunar
6.2.0-34.34 has been released ** Changed in: linux (Ubuntu) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2025040 Title: increased power usage after upgrade from kinetic to lunar Status in linux package in Ubuntu: Fix Released Bug description: Hi I have just upgrade and power usage is double or more under lunar. Kernel version went from 5.19.0-43 to 6.2.0-20. Running powertop, I see that C8 is being used with 5.19 but 6.2 does not go to a higher power saving state than C3. I tried the Ubuntu kernel from jammy ie 5.15.0-73. It also uses C8. I have also tried the 5.15.108 & 5.10.17 mainline kernels. Both of these do not go to higher power saving state than C3. All these tests have been run on the same partition ie. only the kernel version has changed. Laptop is a HP 15s-fq4011TU 11th Gen Intel with Tiger Lake Iris Xe graphics. So it seems to me: 1) Ubuntu has applied a patch to the mainline kernel that improves power saving in 5.15 and 5.19 2) This patch either hasn't been applied to 6.2 or no longer works. Could you pls let me know what other info you need or what I could look at next?

I see that commit "wifi: rtw88: correct PS calculation for SUPPORTS_DYNAMIC_PS" has been picked up in the update to upstream stable 6.1.34 and is in the master-next branch of the lunar git repo. i'll test when the next kernel is built. ** Package changed: linux-hwe-6.2 (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: Confirmed => Fix Committed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2025040 Title: increased power usage after upgrade from kinetic to lunar Status in linux package in Ubuntu: Fix Committed Bug description: Hi I have just upgrade and power usage is double or more under lunar.
