You would do better to inquire on the HRT mailing list: http://lists.sourceforge.net/lists/listinfo/high-res-timers-discourse HRT support (from http://sourceforge.net/projects/high-res-timers/) was never accepted to mainline. It works on Ebony (PPC440), but I guess it is OK on others since it uses the PPC time base. I recommend you get the latest from CVS, which is against 2.6.12. Older versions have CVS tags. -Geoff
