With the system running in init 1, and cool n quiet disabled in the bios, a sleep(N>0) results in the run_time value afterwards always being nearly the same value of ~995000 on my athlon64, similarly, my server an athlon-tbird, which definitely has no power saving features, hovers at ~1496000 Obviously since these values are nowhere near 10000, the loops_per_ms benchmark runs forever, has anyone seen/read about sleep on amd machines doing something odd? Can anyone else with an amd machine confirm this behavior? Con: should we attempt to get the attention of LKML to see why amd chips act differently? -- Gabriel Devenyi ace@staticwave.ca
