Upon further testing, it seems like the likely cause for this is 2.6.21+ having BETTER power management support - and, thus, entering the lower C-states. I did test disabling tickless operation, and it made the issue worse. I decided to close this because the issue also exists in Mac OS X and the lack of a problem in 2.6.18 seems like an aberration. |

OK - my bad. 2.6.18 was doing proper power management on Etch. Thus, I'm reopening this bug as it seems this CAN be worked around, though it is a hardware issue. |

Your bluetooth controller and trackpad are waking up the CPU regularly, which is what results in the noise. Disable bluetooth to improve this. |
