[Padmini Jaikumar (padmini-jaikumar)]

Hello,

I am quite new to linux. I have a dual boot machine with windows 7 as the second OS. I have a Dell Studio 14z.

I have ubuntu 9.10 amd64 distribution. This is the second time this bug has appeared. The first time it appeared, ubuntu worked for a while after there was an error. After GRUB loading, it went straight to operating system not found. I formatted my machine and installed both windows 7 and ubuntu 9.10 again.

Now this bug is appearing for the second time. Can you please tell me what I should do to fix it? I really want to continue using Ubuntu. Also, do you recommend that I install Ubuntu 9.04 amd6x/ Ubuntu 9.10 32 bit version to avoid this error.

Thank you in advance.

[Jeremy Foshee (jeremyfoshee)]

Hi Lukas,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 549841

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

This bug seems to have been around a while:
http://dunedin.lug.net.nz/forums/showthread.php?t=451783

What I also noticed is that I am losing 1min per hour (system clock falls behind hardware clock.)

Are these perhaps related?

Also, why is this bug still marked incomplete?

[Tim Gardner (timg-tpi)]

Lukas - Two things you can try:

1) Install an LTS backported 2.6.35 kernel from http://ppa.launchpad.net/kernel-ppa/ppa/ubuntu
2) Boot with 'clocksource=tsc' (edit /etc/default/grub or hold the shift key to catch the grub boot prompt)

[Lukas Koranda (lkoranda)]

Hi TIm,
thanks for suggestions. It looks that issue is gone. Not sure if it is latest lucid updates or BIOS update which I did few weeks ago (officialy related to overheating).

[Tim Gardner (timg-tpi)]

Seems to have fixed itself.
