p4-clockmod and "N60 errata" patch

Sorry...

"since there aren't any cpu which lowest frequency is under 0,4 Ghz)"

should read:

"since there aren't any cpu which lowest frequency is higher than 0,4 Ghz"

Ill look into this

Please revert this change - my laptop crashes (hard) with the lower limit.

I confess that I didn't entirely understand what the erratum meant (and I still don't) when I wrote the N60 errata patch last year, as I'm nowhere near an expert on the Pentium 4 architecture. There may very well be some other change that would enable more efficient use of power on affected systems. The way the kernel's power management code uses the processor now, however, requires the 2 GHz limit.

The erratum is available at the bottom of page 49 of the pdf at http://download.intel.com/design/Pentium4/specupdt/24919965.pdf if someone better at Pentium 4 internals wants to take a crack at a more efficient patch.

Hi, I am sorry but I can't reverse this change (i don't know how to do it). I just submitted a bug and a possible solution. In June I had a discussion with an engineer from University who is an expert about cpus. I told him about my problem that is my cpu not going under 2Ghz even if it has not bug "n60", and he told me that only little production of PIV had this bug and that anyway it was possible to lower way under 2 Ghz, safely.

So I just found the lines of code in p4-clockmod where it sets the lower frequency and recompiled some kernels with lower frequencies and I tested on an old notebook (Acer Aspire) that had cpu with bug. I found that it was only crashing (hung and reboot) at lowest frequency, that was 400 or 500, I don't remember... but it was not 2Ghz... I don't know about this 2Ghz limit that you say. Maybe behaviour differs with different power management.

So I just proposed to resolve the bug putting 700Mhz instead of 2Ghz.
It is my first bug reporting and I didn't know that they would have put in the kernel my code without any more testing. I do not have any lab or similar to do proper testing....

So... what shall we do? I am not an expert...
I believe that perhaps they should change kernel power management instead of limiting frequencies....

Might it not be better to keep 2GHz as the default lower limit, but to allow this to be changed in the kernel config?

Better still would be to be able to specify a new lower limit when the module is loaded, e.g.

modprobe p4-clockmod minfreq=700000

This bug also affects linux-image-2.6.17-11-386 from Ubuntu edgy-security repository.

I am assigning this bug to the 'ubuntu-kernel-team' per their bug policy. For future reference you can learn more about their bug policy at https://wiki.ubuntu.com/KernelTeamBugPolicies .

The 18 month support period for Edgy Eft 6.10 has reached it's end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task.

Hardy Heron 8.04 was recently released. It would be helpful if you could test the new release and verify if this is still an issue - http://www.ubuntu.com/getubuntu/download . You should be able to test your bug using the LiveCD. Please let us know your results. Thanks.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

I tested my laptop with the LiveCD of the Beta version of Intrepid. The p4-clockmod module is not loaded by default, but if it is loaded, the laptop crashes as it did before.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

This bug report was marked as Triaged a while ago but has not had any updated comments for quite some time. Please let us know if this issue remains in the current Ubuntu release, http://www.ubuntu.com/getubuntu/download . If the issue remains, click on the current status under the Status column and change the status back to "New". Thanks.

Totally disagree. If you didn't want to hear anyone you could just mute everyone but friends by default.

Trash talk was fun and mostly all in good fun. I met a lot of cool people in random lobbies back then, and that never happens any more. Mute was always an option if someone was being too annoying. Overall I feel much less of a sense of community from multiplayer games as a result, and in turn the games have less of a personality.

I do think private chat as an option is a necessity though.

Clearly it reduces the value of the firm by exactly the same amount as the dividend - neutral from the shareholder point of view.

I think the perception of a consistent dividend is that this is somehow "free money" but actually it is better if the company has growth opportunities and invests the dividend. Hey if I want cash I can sell some shares myself. I don't need it forced on me.

I am a novice at this . I don't even know what a double din is . I have seen some stand alone backup camera systems on e-bay that come with the screen . Can't i just install one of those and but a Bluetooth capable stereo system separately . Would something like that work or am I asking for trouble ?

I'm exactly the opposite. I appreciate fallout for what it does right. Storytelling is fantastic and the environments, are very immersion though it can get a little boring to just run through the desert. But I can't stand that you can shoot a super mutant 5 times in the head and it loses like half its health. Combat honestly feels like the weakest point for me in the fallout series. Which is bad because it's one of its main game play mechanics. But that's what mods are for I suppose. You do run into the same issue in elder scrolls but I always care less for some reason.
