Yes, I already tried kernel 3.13RC1 a couple of days ago, and it was the same. I tried the one from the Ubuntu kernel PPA, not the one directly from kernel.org (as I mentioned in an earlier post, I can not compile the kernel on this computer).
I tried many many kernels in an attempt to isolate the issue. In the end it appeared to be kernel configuration differences only, as mentioned in my first post. Hope this helps. -- 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/1254920 Title: CPU utilization / accounting issues Status in “linux” package in Ubuntu: Incomplete Bug description: The issue is on a Trusty 32 bit server edition. It is the very very old computer that I use for minimum requirements testing. The issue is CPU user, sys, idle, and wait information makes absolutely no sense at all. For example with the commands "top" or "vmstat" I believe I have isolated the issue down to kernel configuration differences between Saucy and Trusty. I used the two otherwise same kernels from the ppa to come to this conclusion (after many many other kernels and such were tried). References: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-trusty/ While there are a lot of configuration differences that are obviously not the issue (or so I think), there are many that I don't know if they could be or not. The computer I am using is too pathetic to compile the kernel (it takes 34 hours, and then it gives up before finishing anyhow). I will attach the config difference file in a moment. Automatic bug stuff has never worked for me on any of my computers, but I'll attach the other stuff asked for shortly.
