teejayhoward Posted December 13, 2006 Share Posted December 13, 2006 (edited) I just finished installing 10.4.8 for the first time on my system. (Installed natively via DVD-R) Had nothing but problems trying to get it to work with SATA (corruption), eventually gave up and installed an old 10GB PATA drive I had laying around for the past 5 years or so collecting dust. I'd like to say I love it, but I'm afraid I can't... There's a serious stuttering going on. Activity Monitor shows kernel_task consuming 100+% of my CPU, and I'm sure that's the reason why. After a couple of hours of searching, I came across two basic "answers" to my problem: 1) Delete or move AppleTPMACPI.kext. 2) Boot with platform=X86PC or platform=ACPI or platform=ACPI|X86PC Well, there is no AppleTPMACPI in my System/Library/Extensions folder, and booting with the platform flag ain't helping me any - I'm still experiencing an issue. Is there anything else I should try? My system specs are below: AMD Opteron 165 at stock speeds 4x1GB G.Skill DDR400 at DDR333, stock timings DFI nForce4 Ultra-D BFG 7800GTX 256MB X-Fi XtremeMusic (That obviously isn't producing any sound) Seagate 10GB PATA drive SATA WD Raptor 150 (XP64 drive) SATA WD 160GB FAT32 scratch/transfer drive SATA WD 320GB NTFS dump drive The problem exists even with the SATA drives completely disconnected.

mifki Posted December 14, 2006 Share Posted December 14, 2006 TPM is out of the question nowadays, hmm, if your opteron is dual core try booting with the arguemnt: cpus=1 Link to comment https://www.insanelymac.com/forum/topic/35762-kernel_task-at-100/#findComment-254540 Share on other sites More sharing options...
teejayhoward Posted December 14, 2006 Author Share Posted December 14, 2006 TPM is out of the question nowadays, hmm, if your opteron is dual core try booting with the arguemnt: cpus=1 cpus=1 changed the Activity Monitor graph to only show a single graph. I'm assuming it told the OS to only use a single core? At any rate, kernel_task is still consuming massive amounts of CPU time. (90-98% now) Is there any utility out there that will show me the individual threads kernel_task has, and which one of them is using what percentage of the CPU? Even when booting with -x, kernel_task is eating cycles. I also tried removing my X-Fi. Didn't do any good. Don't suppose there's any way to make the X-Fi work in OSX86, eh? Err, got sidetracked. Anyway, unfortunately, your suggestion didn't fix my problem. Any other ideas?

teejayhoward Posted December 14, 2006 Author Share Posted December 14, 2006 Overclocked my machine a bit (Extra 50Mhz FSB) and kernel_task is now using 0.6% of the CPU. Woot!

starblob Posted January 4, 2007 Share Posted January 4, 2007 (edited) I'm using this same one I think, and I'm having exactly the same problem. I have an AMD Athlon 3200 though. Kernel_task runs at almost 100%, and i dont know how to stop it. has anyone worked out why it does this and how to stop it? thanks Edited January 4, 2007 by starblob Link to comment https://www.insanelymac.com/forum/topic/35762-kernel_task-at-100/#findComment-268160 Share on other sites More sharing options...
