I know it's a couple of days old, but I only just found out about the latest Netkas kernel. Apparently it fixes shutdown and reboot, so finally no more holding down the power button to turn off! (Can be found on Netkas' blog)

Yeah, I have it installed and it works great. Shutdown and Restart work, and even though the kernel doesn't have sleep functionality built into it, sleep still (partially) works in ACPI S1 mode.

Yep. I just installed it too. Working fine and dandy. Also, sleep seems to work in S3 (Suspend To RAM) for me.

Weird...Probably just my board Oh well, I don't use sleep anyway

ok I got this too but how do I install it , it keeps giving me directory not found anyone pls

This kernel breaks S3 on the Intel Bad Axe 2; S1 works, however. It fixes a lot of problems on the BA2 under 10.5.2, along with the Macdotnub SMBIOS-27.

Copy over the mach_kernel file you downloaded to the Desktop. Then run these commands from Terminal (Applications/Utilities):



Close terminal and reboot

cant get it up work on Dell 530s intel G33 chipset, when i try to shutdown..it does reboot instead.

It doesn't work for everyone as you see in the comments for the post in netkas's blog

Mine works too! sleep works with mine too but apparently all my external drive log out when i sleep cause when i wake up all drive remount and device not bla bla bla error. ohh and safari quits

You need to repair permissions too.

On my P35C-DS3R, it breaks S3 sleep(black screen on wake), but fixes shutdown/reboot. S1 sleep results in the HD/CPU/RAM shutting off, but the case stays on, as well as the graphics card.

Hmm, what's the meaning of PC_EFI if we still have to use a modified kernel?

You can use unmodified kernel extensions. You can also have a GUID partition table too.

hehe i got shutdown to work finally with this Acpiplatfourm.kext Click to view attachment and using this new Netkas 9.2.0 kernel.

Ok, I guess it's good to have a second partition where you can try new updates. If it stops working you just boot with the other and fix the broken one from there.

2 things:

1: When installing, do you extract the Mach_kernel from the .zip file before doing the steps ~pcwiz stated?

2: How can you tell what kernel you have? I upgraded to 10.5.2, and I upgraded my Kernel, so I assume I have 9.20, but I think it would be useful if I knew a way to double check. Thank you!

Same here.

Dax,

Same thing here on a DS3P.

Wayfarer,

Yes you extract the file before doing the Terminal stuff

You can check by running this command on terminal:

uname -a

1 when you dl the kernel, it is uncompressed automatically ( check your garbage, there is the .zip, and in the downloads folder is the mach_kernel

2 : in the teminal, quote uname -a and you should see wich kernel version U have .
( also in about this mac , software )

Sorry for being noob/thick/blind/asleep, but how doyou get hold of this file ?

Thanks

M

lol, pcwiz, you're always here. Thank you, that worked perfectly.

immarco,

Use an IRC client like Colloquy to connect to irc.osx86.hu room #10.5 and the links will be listed at the top.

what problems are you experiencing with BA2, vanilla kernel, and 10.5.2?

thanks.

Got it, thanks ~pcwiz

Hey, if this kernel did nothing for you, like with my computer, how would I uninstall it and go back to using the Vanilla kernel?

added speedstep-less, sleep kernel.

If you saved the original kernel, just replace the new one and repair permissions. Right?

EXCELLENT netkas. What we need now is a kernel with

- Sleep
- Shutdown and Restart
- SpeedStep

ALL IN ONE. If that is possible. I'm sticking with the Speedstep kernel for now since Sleep isn't important to me.

Wayfarer,

Hoping that you backed up your kernel, you just copy it back over. And even if it did nothing for you, there is no harm in leaving it.

Sabr,

I know its typical to repair permissions but what I found was that after I repaired permissions after I installed the new kernel, no permission errors related to the kernel popped up in the log...

I guess it varies then, because most of the time the permissions have changed. I do on occasion have no incorrect permissions after replacing a kext or something though. I just feel it's safer to repair permissions afterwards.

Didn't do anything for my shutdown/restart, specs in sig.

Thks pcwiz , now how do i fix permissions for just this one thing without using disk utility, which sees what is wrong but never repairs anything, in my case anyways.

Thks again

Applications > Utilities > Terminal

And then enter (letter-for-letter):
diskutil repairPermissions /

With the sleep kernel netkas just released, my sleep works now, and the model shows up as MacPro and MacPro 3,1.

I don't think that's possible. mac.nub and netkas both explain that sleep won't work with this implementation of speedstep. I'm fine with that. I'm just absolutely greatful that these guys are so working hard on their own time to benifit us. Thanks netkas

I'm glad too. I knew there must have been something preventing the creation of a perfect kernel

Sorry if this is a stupid question but can i use the 9.2.0 kernal if I dont have EFI??

As i selected SSE2/SSE3 during my kaly install

I think so, but the safest way to find out is not to replace your mach_kernel, but rename this one to mach_kernel.toh or something similar. Then place it in your root directory, repair permissions, and at the Darwin prompt, type "mach_kernel.toh" and it should boot using that one instead. Then you can overwrite the original mach_kernel if it works.

Remember - always make backups just in case!

can someone please PM me a download link for the kernel cos I dont have or know how to use and IRC programs .

Wait, you want to mess with critical ring 0 system files, but can't download and use a simple IRC program? There is just something wrong with that on so many levels.

anyone here have had succes on using speedstep on DS4 motherboard?
I've tried with differents powermanagement bundle, but with the new kernel and new ACPI fix no succes here.

here also not

I have 2 mach kernels one is just mach_kernel and the other mach_kernel sse2 i used the first on my machine p4 2ghz ,and it says kernel 9.2.0.0 i guss i should leave it as is?

Thks

I would use the SSE2, but if it's working I suppose that's fine, just leave it!

Damn, using the sleep kernel sleeping mode finally works, BUT now sound is choppy and my clock is running too slow!? I mean, when I start OSX time is fine because it syncs with the internet time server, but from that point I'm continously "loosing" time :-/ I think the new kernel has problems finding the right FSB speed? So I had to switch back to vanilla kernel.

works amazing for me! as we speak im reinstalling macosx to dual boot with xp D:

ty ty ty to whoever did teh update! ^__^

ok I still have to hit reset on my machine to restart leopard, any fixes pls?
Also my Realtek alc650 sound is not working, any ideas on kexts or other things I could use?
Thks
Maybe i'll leave mach alone and not put mach sse2??

i now have flawless shutdown and sleep functions, thanks netkas, thanks for your time!!

this kernel rocks

everything is now working on my 2 computers ( amd & intel )

thanks a lot !!!

I can't find his blog >.<
