k, this is bugging the sh*t out of me! Jaunty has gotten progressively less stable since Feb!

I am on a Thinkpad X61 (generic intel hardware, integrated graphics) running 64bit, and have been grappling with freezes for the last couple weeks.

1) this is not a kernel freeze, you can move the mouse, but no keyboard responses, i.e., caps lock has no response. When I ssh into the frozen machine, you can login, htop shows you that nothing suspicious is going on at all. No bad cpu usage, no bad mem usage, etc.

2) but the onset of these freezes on powertop does seem to be associated with random CPU frequency and p-state hikes, i.e., out of the god damn blue, with no application running, CPU runs like hell in powertop and burns lap

3) this is not kernel specific, I have using bleeding edge kernels from ubuntu and compiled 2.6.29, problem persist

4) I theorize problem is in the Xorg drivers, but the bleeding edge intel xorg drivers freezes as well

5) the sata controller does seem to have suspicious activities sometimes, though this is not necessarily connected to freezes. The only time I noticed sata problems, the sata problem preceded the freeze by about 20 mins.
