i only have one kernel "mach_kernel " and i never edit the boot.plist i have one i build and i always use the same
funny i used all versions of lion with no problems (only had problem with ati kexts but was fixed with no problems) and now i update from GM to 10.7.2 and i get stuck in boot...
i now removed now all my kexts (just leaved fakesmc.kext) , i even removed ati kexts and i still have the same problem... in the last line i get stuck doenst open the graphic interface
maybe is something related to ati?
Then it may be unique to your particular hardware/kext - are you using a non-standard AMD GPU driver kext (as opposed to an enabler/injector) with Lion GM? While I needed an injector, an enabler, and a modified version of ATY_Init (and a copy of the ROM from my GPU) with Snow, I needed only the injector (ATI5000Injector.kext) with Lion.
Graphics is VisionTek AMD HD5450 PCIe 512 MB (the fanless PCIe basic desktop version).
