oldnapalm Posted March 17, 2012 Share Posted March 17, 2012 kernelcache is not being updated and Chameleon doesn't load it because it's older than Extensions folder /System/Library/Extensions is more recent than KernelCache (/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache), ignoring KernelCache Looks like the problem is in AppleThunderboltNHI.kext which has unresolved symbols kxld[com.apple.driver.AppleThunderboltNHI]: The following symbols are unresolved for this kext:kxld[com.apple.driver.AppleThunderboltNHI]: IOPCIDevice::protectDevice(unsigned int, unsigned int) kxld[com.apple.driver.AppleThunderboltNHI]: IOPCIDevice::setConfigHandler(int (*)(void*, unsigned int, IOPCIDevice*, unsigned int), void*, int (**)(void*, unsigned int, IOPCIDevice*, unsigned int), void**) kxld[com.apple.driver.AppleThunderboltNHI]: IOPCI2PCIBridge::adjustPowerState(unsigned long) Link failed (error code 5). Prelink failed for com.apple.driver.AppleThunderboltNHI; aborting prelink. Failed to generate prelinked kernel. Removing the kext, kernelcache is updated and loaded normally sudo mv /System/Library/Extensions/AppleThunderboltNHI.kext /System/Library/Extensions/AppleThunderboltNHI.kext.orig sudo kextcache -prelinked-kernel Loading Darwin 10.8Loading kernel cache /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache Read HFS+ file: [hd(0,3)/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache] 4096 bytes. Read HFS+ file: [hd(0,3)/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache] 28368802 bytes. Edit: actually the problem only happens if I'm using this IOPCIFamily (to see verbose boot after "PCI configuration begin"), using original IOPCIFamily there's no error creating kernelcache. 1 Link to comment Share on other sites More sharing options...
tdtran1025 Posted March 17, 2012 Share Posted March 17, 2012 The OBVIOUS welcome change is IOPCIFamily.kext, which is back to supporting an array of motherboards. I could not boot straight to a new install on 1 of my machines which has atypical ICH10R chipset. Now it does it with no boot parameter at all. What a relief. I even managed to install to RAID0 volume that has always been tricky since Lion. I noticed something about a Library of graphics cards. On 1 machine that has NVidia 9600GSO, fan power is on Max when Desktop appears. DVD players also is not loading. But beyond that, everything is smooth. Again software RAID support is a major plus for me. In fact, I am making it my day-t-day OS since it seems stable enough. I will try ATI cards right now.

mitch_de Posted March 18, 2012 Share Posted March 18, 2012 I get (frist ever for me) an reboot booting from the USB Install Stick - without any KP / others things listed on verbose screen. C2D / NV 9600 GT. I will look furhter - DP1 install (same process worked). EDIT: Was the Chameleon 1890 ML bootloader. Even listed as ML ready (used the Chameleon thread here) it doesnt work rebbots- I crosschecked that if i try to boot my already on HD ML DP1 which also reboots. Using an older 1831 ML chameleon didnt reboot. BUT: As i reached first menue to select language - doesnt matter which lang i select it showdowns?!

mitch_de Posted March 18, 2012 Share Posted March 18, 2012 THANKS for reporting same problem: shutdown at first OS X setup menue of language settings. Perhaps better to discuss / search solutions in the ML Install Thread? I will go there . http://www.insanelymac.com/forum/index.php?showtopic=277226 Link to comment Share on other sites More sharing options...
Kynyo Posted March 19, 2012 Share Posted March 19, 2012 @ the installation process i've not encounted any problem. As bootloader I used just Chimera 1.8 without any error mentioned here. Everything just works flawless here! (Monitor Sleep issues also resolved in DP2). Link to comment Share on other sites More sharing options...
