[Bug 535572] Re: System hard locks with Lucid

[Ancoron Luziferis]

For some time now the system runs somewhat stable. I enabled Cool &
Quite in the BIOS but disabled C1E support.

If I enable C1E support than I immediately get those big lags back
(doesn't depend on a specific kernel as I tested 2.6.32 up to 2.6.34)
and I presume that after some time the machine would lock again. With
C1E disabled I get the following output from my script which is much
nicer:

...

[2010-05-28 07:05:22.528] missed 28 ms
[2010-05-28 07:05:23.555] missed 27 ms
[2010-05-28 07:05:24.583] missed 28 ms
[2010-05-28 07:05:25.610] missed 27 ms

[2010-05-28 07:05:31.774] missed 27 ms
[2010-05-28 07:05:32.802] missed 28 ms
[2010-05-28 07:05:33.829] missed 27 ms
[2010-05-28 07:05:34.858] missed 29 ms
[2010-05-28 07:05:35.885] missed 27 ms
[2010-05-28 07:05:36.913] missed 27 ms
...

So the "lags" are now considered to be stable (26-29ms). But C1E support
is a nice thing regarding power management so this still is an issue and
probably will be for Ubuntu 10.10.
