[Ubuntu-x-swat] [Bug 524281] Re: Tens of wakes per second in [kernel scheduler] Load balancing tick on Core 2 Duo even with only 1 core enabled
Yes I have also seen a similar degradation between the two kernels. What is notable in your case and mine is that the kernel interrupts are labelled differently between the two cases. There are actually fewer load balancing ticks in the later kernel but other categories eg [extra timer interrupt] are chewing up power. So something appears to have changed but not in a good way and focussing solely on [kernel scheduler] Load balancing tick is not appropriate. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/524281 Title: Tens of wakes per second in [kernel scheduler] Load balancing tick on Core 2 Duo even with only 1 core enabled ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

The last two comments on this bug are contradictory. Checking powertop with the 2.6.38 kernel for natty versus earlier kernels shows for me that the *type* of kernel interrupt has changed but the number of them has not and has increased if anything. I think this bug is serious and getting worse and requires the attention of a kernel developer. It reflects badly on linux in general if power consumption is increasing markedly while performance is not markedly increasing at the same time (which appears the case on the phoronix benchmarks). To solve this requires someone familiar with the kernel to report it on the kernel bugzilla. There has been some discussion of the issue on lmkl but it looks very inconclusive and low priority to me. I don't know why exactly. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/524281 Title: Tens of wakes per second in [kernel scheduler] Load balancing tick on Core 2 Duo even with only 1 core enabled ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 464591] Re: upgrade breaks graphic drivers and x, preventing login or startx
I had this problem of flickering while DRM compiled a new kernel module against the latest Karmic kernel. The flickering lasted a considerable time but after a few minutes presumably when the compilation had finished the system booted to a standard gdm screen and set the resolution properly. I checked and the nvidia module was loaded and acceleration was enabled perfectly fine. The mad flashing for several minutes was however very disturbing I must say and gave the impression of a video driver mismatch. -- upgrade breaks graphic drivers and x, preventing login or startx https://bugs.launchpad.net/bugs/464591 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
