Kernel Panics LawlessPPC

[ahoytharmatey]

Hey everyone. Been on this forum many times but today i have a need to post. I am running LawlessPPC 10.5.4 on an AMD machine. All goes well except for when i un-zip a file using the built in zip (archive utility) or macpar deluxe, or going on to newsgroups. I can make the OS kernel panic on queue by doing one of these activities and for the life of me cannot figure out why. Ok now here are my computer specs:

AMD Phenom 9950
MSI K9A2 Platinum Motherboard
Corsair 4GB of Ram
Radeon 3650 Video Card
500GB Western Digital Drive
Samsung DVD Drive
Sony Blu-Ray Drive (Not seen by OS X, but i know why and thats totally ok)
Antec 850W power supply.

WHen i installed the LawlessPPC i checked only the drivers i needed and nothing more. I have no idea what kernel im using since i a) dont know how to find out and b) doesnt show you when you install the OS. I have also run the Universal Tools as well with no fix. Has anyone else seen this? Is it my hardware? Is it the OS? SHould i try another OS? Other than LawlessPPC, what have you guys found works great on an AMD Phenom? THanks a lot guys.

Should you try another distro? You always can grab newer one like iPC. But first things first - it may ( at least i think it may ) be related to kernel. What version are u using ? Install newest Voodoo kernel and try again - but im not sure if it works with 10.5.4 system, so if not - then try 10.5.6 distro.

would i go about it by just installing a stand alone kernal? or get a newer distro and install the kernal from there? sorry for the ignorance.

P.S. I tried iPC but it would not boot on my system for whatever reason.

[ahoytharmatey]

also i know that having an intel machine is much safer for obvious reasons in terms of installing and doing updates, i have an intel machine. would it be worth while to just use that machine? if so, what distro do you all recommend for an intel box? any? and am i right to say that you can do updates from software update safely with an intel machine?

[LawlessPPC]

get the latest voodoo kernel 9.5 then upgrade the system to 10.5.5. The other i will add is you will have to reinstall the graphics drivers after the update. So once everything has updated you will need to boot with -v -f -x then from there install graphics driver. Otheriwse you will just get a scrambled screen because apple will replace your current driver.

sorry for the ignorance, but how do i go about getting the new kernal? download a new distro-with that kernel?

There you go, kernel with an installer. Just download it and run the installer package.
Remember that it is for 10.5.5 and higher and may not work properly on 10.5.4 ( though it worked for me )

thank you so much for the help. hope this fixes my kernel panics. thanks again to everyone.

[ahoytharmatey]

just installed and still get kernel panics. going to try another distro to make sure its not hardware. thank you.

[LawlessPPC]

ive just realised you have 4gb of memory that will be your problem. With over 3.5gb of memory osx will panic randomly unless you have a 64bit chipset driver. Take a gig or 2 out and see how it goes!!!

[ahoytharmatey]

Thank you so much for that help lawless. This morning arond 2am I managed to get it working. I installed lawlessppc and then installed a few kexts from iPC from the desktop ontop of lawless. ThNk you so much for your work. If it panics again, I will def remove some memory. Thanks again!

[ahoytharmatey]

does anyone know of a 64bit chipset driver for an msi k9a2 platinum motherboard which is a via chipset, south bridge 600 and is an 790FX board. thanks.

this should do the trick same as im using

[ahoytharmatey]

thank you so much lawlessppc. i will def give this a try. just downloaded it now and will let you all know. thanks again for all your help and work.

quick question lawlessppc, i have the same motherboard as you and just curious. when you install the lawlessppc distro, it installs the vanilla kernel. when you updated to 10.5.5, did you use any patching or just download the update from the website and install it. would you recommend the vanilla kernel over the voodoo on with our setups?

it doesnt install the vanilla kernel its just named the same if the kernel is named differently it can break some programs as they expect it to be called mach_kernel. I use the voodoo kernel but i have named it to mach_kernel your best to download and install this

[ahoytharmatey]

oh ok gotcha. i currently have the voodoo kernel installed ontop of your lawlessppc distro. sorry if im missing something, but you say to download the update 10.5.5 from the website and apply it or...

there should be no need to patch any files for use with amd if you use the voodoo kernel this is the main benefit of using it. It patches on the fly

I've got 4gig of ram on a Dell C521 with an AMD64 running iDeneb 1.3 that's giving me random kernel panics. I don't want to be pulling ram out, whats the best software solution? I'm not sure whether to use the 64bit kext or limit the amount ram

[antwan911]

add maxmem=3072 to your boot plist, saves you removing the ram.
