build a new one which includes it.</blockquote><div><br>You're certainly right.<br>I thought Lenny defaulted with HPET support.<br>Either, this is not true or my hardware doesn't support it or my configuration doesn't enable it.<br>

<p>If you have an ICH6 or higher chipset, you should be fine. Some support exists on ICH5 chipsets.</p>
<p><strong>How do I know if HPET is really active on my system?</strong></p>
<p>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:<br>grep hpet /proc/timer_list<br>If this doesn't show the word "hpet" then it's not active.<br>The
BIOS may hide this functionality as well. You should try the
force-enable HPET patch from <a href="http://linuxpowertop.org/known.php">http://linuxpowertop.org/known.php</a>."</p><br><p></p>I tried it but it doesn't show anything such as "HPET is disabled" or "Your hardware can't support HPET".<br>
<br>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").<br><br>Thank you very much.<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
