[Bug 1544798] Re: high load with on 4.2.x+ kernels for Intel Mobile processors

2016-02-19 Thread Ben Howard
Dropping this bug. After upgrading to Xenial, I found that the 4.4 kernel from the archives has reasonable load. The issue is only seen with mainline kernels. ** Changed in: linux (Ubuntu) Status: Triaged => Invalid -- You received this bug notification because you are a member of Ubuntu

The 4.2.0-x kernels are being installed via apt. Where the 4.2.x was installed from the mainline kernel ppa. The last 4.2.x kernel that I tested was at http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.4-wily/ -- You received this bug notification because you are a member of Ubuntu Bugs, which i

Are you getting the 4.2.0-x kernels from here: http://kernel.ubuntu.com /~kernel-ppa/mainline/ ? And the 4.2.x-wily kernels from launchpad? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1544798 Titl

Actually, for the 4.2.0-x kernels, the load is fine; it is with 4.2.x-wily kernels where I saw the high load. I tested the 4.2.4-wily kernel and hit the issue, but did not test the others as they were marked as "unstable." -- You received this bug notification because you are a member of Ubuntu B

In comment #5, did you mean the 4.2.0.x kernels are the first kernels that exhibit the high load? If so can you test these two kernels and confirm that v4.1 final has an acceptable load and 4.2-rc1 introduces the high load? If that is the case, we can bisect between 4.1 and 4.2-rc1. -- You rec

After testing every kernel under the sun, I found that 4.2.0.x kernels appear to the last ones with normal idle load. I tested all the 4.2, 4.3 and 4.4 kernels marked "-wily" and found that they all had the increased load. I didn't test any of hte unstable ones. The load averages are, however, more
