Hello everybody, I'm currently trying to get linux kernel 2.6.21-rc6 with the RT-Preempt patch running on an embedded board with an Geode GX1 processor. The kernel itself boots up but cannot initialise ACPI. And seems like that's why the high resolution timer cannot be started, so the RT-Preemt functionality does not work correctly. On a "normal" x86 desktop system (amd athlon) exactly this kernel with the Preempt patch is running fine. When I'm booting linux 2.6.18 with RT-Preempt (patch-2.6.18-rt5) without using acpi it's working on the GX1 system. Is there a way to run recent linux kernels and recent RT-Preempt patches without using ACPI? Or should I stick to 2.6.18-rt5? kind regards, --peter - To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
