liaoliaola Posted October 31, 2009 Share Posted October 31, 2009 Hi, I just happened to solve the kernel_task high cpu > 90% issue on my PC. My configuration: CPU: Intel C2D E6300 2.8G Mainboard: Intel G41, ICH7 Video card: nVIDIA GeForce 7300GT OS X version: iATKOS_v7 Problems and fixes: 1. needs to input cpus=1 when booting, fixed after applying cpus=1 patch in iDeneb.v1.5.10.5.7 installation CD 2. video card driver, fixed after apply the patch here ->NVIDIA_7300_GT.zip 3. kernel_task causes cpu high > 90%, fixed after (1)applying ACPI_SMC fix patch, (2)de-selected all items in Spotlight config, now the kernel_task's cpu is less than 1% 4. it is very slow when booting (about 5 minutes), saying "Interfacenamer: timed out waiting for IOKit to quiesce", no fix yet... Overall, as I am a newbie, this is out of my expectation and I want to share it Link to comment https://www.insanelymac.com/forum/topic/195140-kernel_task-high-cpu-my-situation/ Share on other sites More sharing options...
DunbarXX Posted December 3, 2009 Share Posted December 3, 2009 Where you found ACPI_SMC fix patch? I have the same problem with iATKOS v7 (which is the only distro that installs and runs!!!). My spec: Biostar TP43D2-A7 2GB DDR-II (put on a single slot) Intel Core 2 Duo E7400 NVIDIA GeForce 9400GT The system boots very slow maybe 10 minutes and then is the kernel_task at 100%. Also it is very unstable and freezes often sometimes only hard reboot helps. I've installed with the following options: Voodoo PS/2, Voodoo HDA, AHCI, Realtek R1000 and all the default setting from iATKOS v7 distribution.

DunbarXX Posted December 4, 2009 Share Posted December 4, 2009 Update on my situation! After some time I managed to survive 2 hours without restarting and the kernel_task has calmed down. Now everything works fine sound, video, lan. I'm afraid to reboot, though!
