Maybe that's because I try to configure _everything_ I can as a module, not as built-in. As this has been just a warning on the module install phase I got along and all seems to boot and run fine -- except for some acpi stuff e.g. I've lost thermal zone sensor on my laptop, but that didn't look like a big deal. Yep, that's it... I found the exact messages in my attic, although from an erlier build: WARNING: /lib/modules/2.6.13.1-rt13.0mdk/kernel/drivers/char/hangcheck-timer.ko needs unknown symbol do_monotonic_clock WARNING: /lib/modules/2.6.13.1-rt13.0mdk/kernel/drivers/acpi/processor.ko needs unknown symbol tsc_c3_compensate How about reporting to Ingo and/or the lkml? As you can see its not an AMD64 issue, because I don't have such a beast here. Bye. -- rncbc aka Rui Nuno Capela rncbc@xxxxxxxxx
