zefram69 Posted January 6, 2011 Share Posted January 6, 2011 I've been having random kernel panics since I set up my Hackintosh. The panic has always been with pmap_pv_remove. The other day, it came upon me to remove a stick of RAM and see if that solved my problem. It in fact did. I've been able to do things that I wasn't before (update Apeture, copy an HD movie, etc). I've tried placing the RAM into different slots, but with two sticks it is not stable. I've run memtest and geekbench, and neither found a problem. I can use either of the two sticks, and both work equally as well. I tried: Dual and Single Channel Setting the memory timing parameters manually/automatically Turning on/off Quiet & Cool Turning on/off Spread Spectrum But none of that worked. As my sig says, my mobo is MSI K9AG Neo2-Digital and the RAM is two sticks of Patriot DDR2 800MHz 5-5-5-12 timing 2.0v RAM (PDC24G6400ELK). Any ideas at all??? Edit: as a note, this system ran perfectly stable with Ubuntu previously... Seems to be something with OSX's specialness? The model of the computer is set to iMac9,1.

Gringo Vermelho Posted January 6, 2011 Share Posted January 6, 2011 Maybe you're using an older driver for something. Not necessarily PATA controller.. idea courtesy this topic: http://www.insanelymac.com/forum/index.php?showtopic=127611 Link to comment https://www.insanelymac.com/forum/topic/241964-ram-causing-kernel-panics/#findComment-1616602 Share on other sites More sharing options...

Not necessarily PATA controller.. idea courtesy this topic: http://www.insanelymac.com/forum/index.php?showtopic=127611 I think you may be right. The symptoms are the same. When I go over 2G used, I do get a big ole' crash. This gave me a chance to go through the kexts I use, and the updated versions are: /Extra/Extensions/ACPIMonitor.kext - org.slice.ACPIMonitor (1.0) /Extra/Extensions/FakeSMC.kext - org.netkas.FakeSMC (3.1) /Extra/Extensions/IOAHCIBlockStorageInjector.kext - org.chameleon.plist.IOAHCIBlockStorageInjector (1.0) /Extra/Extensions/NullCPUPowerManagement.kext - org.tgwbd.driver.NullCPUPowerManagement (1.0d2) /Extra/Extensions/NVClockX.kext - org.usrsse2.NVClockX (1.0d1) /Extra/Extensions/PlatformUUID.kext - com.superhai.driver.PlatformUUID (1.0) /Extra/Extensions/SuperIOFamily.kext - org.mozodojo.SuperIOFamily (1.0d1) /Extra/Extensions/SuperIOFamily.kext/Contents/PlugIns/F718x.kext - org.mozodojo.F718x (1.0) /Extra/Extensions/SuperIOFamily.kext/Contents/PlugIns/IT87x.kext - org.mozodojo.IT87x (1.0d1) /Extra/Extensions/SuperIOFamily.kext/Contents/PlugIns/PC8739x.kext - org.slice.PC8739x (1.0) /Extra/Extensions/SuperIOFamily.kext/Contents/PlugIns/W836x.kext - org.mozodojo.W836x (1.0d1) However, I'm still getting panics. Any idea what else could be at fault? Link to comment https://www.insanelymac.com/forum/topic/241964-ram-causing-kernel-panics/#findComment-1619020 Share on other sites More sharing options...

Chameleon 2.0 RC5 has UUID generation built in.
