Thomas, Is this failure specific to NO_HZ, and that is why the "nolapic_timer" fix is i386 only? I'm running 2.6.21-rc5 an nx6325 here in 64-bit mode and I don't see the dramatic boot failure described earlier in this thread. However, I have observed that when running on battery, the LOC falls

The local APIC timer stops to work in deeper C-States. This is handled by the ACPI code and a broadcast mechanism in the clockevents / tick managment code. Some systems do not expose the deeper C-States to the kernel, but switch into deeper C-States behind the kernels back. This delays the local
