(Get the code!)
@ diopez: In my opinion, the problem is the following:
- very early at startup (4sec for me most of the time), something makes the clocksource unstable, raising a "tsc unstable".
- then some process (possibly a process being very offensive on the whatever clock you use), triggers a big slow down (which I experience as a "hpet increasing" being issued and then I have to restart). For me, this process is either linked to ethernet (when I start the computer with ethernet cable in, I often do not reach KDM before the problem arises!!! which means after 1min my computer has already stalled) or to video playback (20min of film watching and I'm screwed...).
Therefore this is must be a kernel issue, possibly not related to ethernet at all, which unbalances the tsc clock at startup till some software screws everything up.
Has everyone already tested the new 2.6.30 kernel issued with Karmic Alpha1 today who can confirm the problem is still there???
