I am not sure what module problem you are talking about. There was a bug in my original patch that caused a link error in most situations where CONFIG_MODULE was set, but this had to do with atomic_dec_and_lock, not preempt_xxx -- what preempt_xxx symbols?
Anyhow, I suggest you grab 2.4.9-ac10 and http://tech9.net/rml/linux/patch-rml-2.4.9-ac10-preempt-kernel-1 and enable CONFIG_PREEMPT and give that a whirl. You should have no problems on a UP system.

Very glad. Especially to hear there are no problems on Athlon.

Great. Data points such as this are welcome. What about the actual throughput? Both I and Nigel (see http://kpreempt.sourceforge.net) benched the patch with `dbench -16' and we both got decent throughput increase.
