how do i boot without cpus=1 ?
Typically I have to boot with cpus=1 to avoid mouse/system lag/stutter. On advice I've booted with cpus=2 and it has worked twice, following posts explain what happen but basically it doesn't seem to work every time.. yet?
with both cores osx is almost unusable. soo slow, but the slowness is worse or less depending on the minute, so its always fluctuating so this problem doesn't happen if I boot with cpus=1. How do I fix it so i can boot with both cores? I have done marvins amd patcher on /system/library and did patching at boot. do i need to do cpuid patching on more then /system/library? using cham rc3, back to mach_kernel.test7 kexts in extra/extensions are smbios.plist AppleUpstreamUserClientDisabler.kext Disabler.kext fakesmc.kext v2 NullCPUPowerManagement.kext OpenHaltRestart.kext Also using azalia from iatkos v7 for audio -------------------- 10.6.1 ~ iATKOS v7 10.5.7 ~ Win 7 RTM AMD 3800+ x2 MSI K8NGM2-FID Nforce 4, ALC880 8500 GT Last edited by spalek83; 10-23-2009 at 11:40 PM. |

That's the "Dual Core" bug. Unless we'll have a kernel with cpu_ids patching - You have to stick to cpus=1 mode. Unless someone knows any solution to this. If not ( and probably that's the case ) we'll just have to wait.

i find that every 1/100 tries, if i shutdown from a session of snow with cpus=1, and boot back into osx without the cpus=1 flag, I get a working snow with both 2 cores of my 3800+ x2 working with no bug/lag/stutter.
But if i shut down and reboot, the bug/lag/stutter is back. and i can't repeat it reliably, only done it twice. most of the time the bug is allways there with a 2 core amd environment Last edited by spalek83; 10-23-2009 at 11:12 AM. |

sometimes ive heard of people being able to boot using cpus=2 ot sure if it applies to a core2 duo tho,. you could give it a try.

the cpus=2 worked on this boot. have both cores working and no mouse/lag/stutter.
awesome [UPDATE] It seems that after many hours the cpus=2 flag made my system shutdown and reset my powercenter at the same time.. no so sure about that,, I explain more in post 39 below. Basically remade dsdt.aml and removed AppleRTC and got boot with cpus=1 with no bug. thanks !!! to taisto, does it work for you with cpus=2 as well? Last edited by spalek83; 10-23-2009 at 10:52 PM. |

Unfortunately no - cpus=2 gives me the same as no flag at all. After 1,5 - 2 hours system starts to work badly ( sound distortion, mouse getting "jumpy" etc. ). I had the same issue with pre-voodoo leopard.

Can you extract a DSDT.aml?

the cpus=2 flag doesn't always work for me. I had my computer running on it last night downloading off newsgroups, and when I woke up my power center had shut everything down like there was a spike... then I rebooted in cpus=2 and bug was there, then booted into cpus=1 and bug is there as well.. WTF!!! So it seems whatever is going on is left in some sort of memory inside osx. Is there anything I can reset on boot that might control this?
[UPDATE] I remade dsdt.aml from inside of snow, rebooted into cpus=1 and mouse bug was gone. In the instructions of the dsdt patcher it said it would make it so I could boot with then removed AppleRTC.kext & AppleCPUPowerManagement.kext running (no disabler), but when I tried that I got kernel panic at boot. I then removed AppleRTC.kext as well as put NullCPUPowerManagement.kext back into /Extra/Extensions So I booted into cpus=1, no bug, yet system info says 2 cores, why? THIS BELOW IS WITH CPUS=1 !!!! Why does it say 2 cores? Are both cores being used? Hardware Overview: Model Name: Mac Pro Model Identifier: MacPro2,1 Processor Speed: 2.08 GHz Number Of Processors: 1 Total Number Of Cores: 2 Memory: 2 GB Bus Speed: 800 MHz Boot ROM Version: MP21.005C.B01 SMC Version (system): 1.30f3 Serial Number (system): SOMESRLNMBR Hardware UUID: 00000000-0000-1000-8000-001346E34902 This stays the same on reboot back into cpus=1. It shows both cores in system properties. Is it possible that it is showing both cores in system properties, but in reality it is not using both cores, how would I check that? Istat menus shows only 1 processor/core's stats.. wonder where else I could look. maybe it is just reporting 2 cores from before, but in reality the second one is not in use??

it shows 2 cores, 1 is active.
