SleeplessMedia Posted December 11, 2006 Share Posted December 11, 2006 I get an error at boot time about 50% of the time where the kernel fails to start one of the cpu's. I don't want to disable Hyperthreading support in my BIOS due to the fact that I still use Windows XP on occasion. Is there a kernel flag that can be set to overcome this annoyance or do I just have to live with it? Also, Is there a way to set the boot device through a flag or some other means as the kernel sometimes hangs at this point in the boot sequence for 30-60 seconds.... Just wondering Link to comment https://www.insanelymac.com/forum/topic/35572-hyperthreading-processor-not-initializing-both-cpus-at-boot/ Share on other sites More sharing options...
Rammjet Posted December 11, 2006 Share Posted December 11, 2006 Try cpus=1 at boot. If it works, add it to the boot.plist under the Kernel Flags parameter.
