You're certainly right. I thought Lenny defaulted with HPET support. Either, this is not true or my hardware doesn't support it or my configuration doesn't enable it. I fished this on Lesswatts.org "*Which chipsets support HPET timers?* If you have an ICH6 or higher chipset, you should be fine. Some support exists on ICH5 chipsets. *How do I know if HPET is really active on my system?* First, HPET must be compiled in the kernel. However, having HPET compiled in the kernel and a hardware chipset supporting HPET doesn't guarantee that HPET is active. You can verify this with the command: grep hpet /proc/timer_list If this doesn't show the word "hpet" then it's not active. The BIOS may hide this functionality as well. You should try the force-enable HPET patch from http://linuxpowertop.org/known.php."; I tried it but it doesn't show anything such as "HPET is disabled" or "Your hardware can't support HPET". Though this raises several questions (mainly, "Why is HPET no enabled ?"), I've got the answer to my initial question ("grep hpet /proc/timer_list").
