Bug Description

On my nvidia box (info to follow plus video) the system is running at double speed.

This wasn't the case in alpha 5 testing where the system was very stable.

I've ubuntu bugged this so you should get most of the reports you need feel free to ping me if there is anything else.

Hi Dave,

I'd like to try to narrow this down to the specific kernel version which introduced this. I believe it was the 2.6.31-8.28 kernel which was shipped with the Alpha 5 images. Can you install and boot back into this older kernel and indeed let me know if this restores the system to "normal" speed. Thanks.

[09:11:14] <davmor2> ogasawara: Meh not working. I've burnt a jaunty cd and it's showing up on that to. So for now leave the bug open I'm going the strip down the box and see if there is a HW fault. Then I'll try again
[12:02:30] <davmor2> ogasawara: Okay that's weird I got an onboard nvidia gfx card on the box that is playing up. So I removed the nvidia gfx card and the speed up problem has gone away.
[12:05:34] <davmor2> ogasawara: I should say I removed the removable pci express gfx card and the problem went away.
[12:06:24] <davmor2> I'm going to assume there fore that it is an issue with the pci express bus for now and have a hunt online see if there is a bios upgrade

I'm closing this bug.

I tried my ati pci express card in the system and after leaving over night had the same issue.

I'm assuming therefore it is an issue with HW and not software. I will look into it more closely over this coming week
