Frixxion Posted July 24, 2010 Share Posted July 24, 2010 Hello Everyone, I have a Dell Lattitude D830 and I have installed the OSX86 Hazard Distro to it. I have upgraded to 10.6.4 without a problem. Everything is running fine. The specs of this laptop are: INTEL CORE 2 DUO T710 MEMORY : 2048MB (2X1024MB) 667MHZ DDR2 S NVIDIA QUADRO NVS 140M WIRELESS : INTEL PRO WIRELESS 3945 (Not working, using an external USB stick) Now I am experiencing a kernel panic when the PC is experiencing heavy load. For example, during extracting rars with SabNZB, I get a kernel panic. I included a picture of the screen. I have already tried several solutions I have found when searching for "appleacpiplatform.kext panic" but these solutions don't seem to affect my problem . Can anyone help me out?

Frixxion Posted July 25, 2010 Author Share Posted July 25, 2010 My laptop also runs very hot, is this because Snow Leopard is CPU heavy? Or is it due to incorrect fan management?

hotcorez Posted July 27, 2010 Share Posted July 27, 2010 My laptop also runs very hot, is this because Snow Leopard is CPU heavy? Or is it due to incorrect fan management? Hi Frixxion, Do you think it might be something like a usb device that is causing the KP? On another note, I know some dell laptops need a tsc sync fix in the kernel, but you would need to check that. (requires patched kernel) If you run try a patched kernel, backup the orignal one to mach_kervel_v cp mach_kernel mach_kernel_v You kernel (even patched dones) must always be called mach_kernel otherwise you will have issue with software like vmware and others. Try booting with cpus=1 to see if that makes any difference. Another possability is a problem with the memory. Are you running this kernel in x86_64 mode or i386? also regarding memory, you can see if limiting that helps, type maxmem=2048 if you have more than 2gb (like 32bit limit) Feel free to google this stuff up if i have made a mistake. Cheers, HC ps you could alway try running the kernel form 10.6.3 to see if that stabalilses things. The key is, was it working fine in 10.6.3 or before? and have you added any hardware since to make it crash. Could be a case of poorly written drivers somewhere down the line. USB modems are ofter rubbish like that, like some taiwanese/chinese brands designed primarily for windoze Link to comment https://www.insanelymac.com/forum/topic/226339-osx-1064-random-kernel-panics-during-heavy-load/#findComment-1519723 Share on other sites More sharing options...
FKA Posted July 27, 2010 Share Posted July 27, 2010 I'm on a roll today so I'm going to say I think this is CPU powermanagment related (You are running HOT!) 2 questions: Are you overclocking ? Are you using NullCPUPM.kext or have CPU PM working ? 2 Suggestions: If you are overclocking go back to nominal settings. If you dont have CPU PM working and aren't using NUllCPUPM.kext then test with NULLCPUPM.kext. If it's still KP'ing, boot to windows and run Prime95 and see if it fails there too ..

scififan68 Posted July 29, 2010 Share Posted July 29, 2010 It's a dell so there's definitely no ocing. To me this looks like appleacpibatterymeter kext isn't working correctly, so you should replace it with VoodooBattery.kext see if that solves your kp. then if it still does I'd run prime95 just like FormerlyKnownAs said.

Frixxion Posted July 30, 2010 Author Share Posted July 30, 2010 Thanks for al the replies guys! My laptop is not overclocked though, I'm just running it with all the normal CPU settings. The Dell bios program doesn't really leave any room for tweaking those settings anyway. To formerlyknowas, I have unstalled NULLCPUPM.kext and I'm still having the same problems, so that's not the solution To Hotcorez, my laptop only has 2 gb ram, so using that bootflag shouldn't do anything right? Thanks though! Where can I find information about "tsc sync"? I have tried googling it, but didn't really find anything useful I'll try replacing appleacpibatterymanager.kext and if that won't work prime95. I'll report my results in a few hours! Thnx guys!

Frixxion Posted July 30, 2010 Author Share Posted July 30, 2010 Solved!!! I installed a few kexts from voodoo and I haven't had a kernel panic for a few hours now! The kexts I installed: - VoodoopowerACPI.kext - VoodooTSCSync.kext I already had the Voodoobattery.kext running. I don't know which of these kexts did the trick, but the combination certainly did the trick! I now have a perfect installation of Snow Leopard !!! Gotta love it Link to comment https://www.insanelymac.com/forum/topic/226339-osx-1064-random-kernel-panics-during-heavy-load/#findComment-1521832 Share on other sites More sharing options...
