linux 2.6.27 kernel won't boot on amd64 hp laptop - need to boot with noapictimer

[Andy Rogers]

Binary package hint: linux-image-2.6.27-2-generic

Hi All

I have been using Ubuntu 8.04.1 and have upgraded to Intrepid Aplha 3 & 4 using kernel 2.6.26 with no problems on my HP Laptop DV6285eu, however since I applied the latest round of Kernel updates from 2.6.26 to 2.6.27-2.3 Ubuntu will no longer boot for me. I also had this same behaviour on 2.6.27-1.1 and 2.6.27-1.2 versions which i also tried to install aswell.

After I have chosen the new Kernel from the grub menu, I get the usuall blank screen which then should goto the Ubuntu splash logo, but it does not it just says at the bottom of the screen on the left :-

Kernel Alive
Kernel is Really Alive

I leave my laptop for a few minutes but it just stays at this.

Does anyone have any ideas how to fix/get past this?

Is this a known bug of this newer Kernel?

Has anyone else experienced this?

I do know my around ubuntu kind of well, but for syste boot logs iam unable to look because i don't know which i should be looking at for further information.

Thanks in advance.

Andy

I have come across this thread http://ubuntuforums.org/showthread.php?t=905908 .

I have since tried the acpi=off as suggested, and this did indeed let my laptop boot with this kernel, but now have the problem of my wireless no longer working, and my screen defaulted to a low res mode and did not use the 177 version of the navida drivers which were installed.

Andy thanks for your bug report. It is being marked incomplete because it lacks required information. Please refer to here for minimum required info:

And some additional info:

When you have added the info please feel free to move the bug to new.

The above attached files were taken when I booted with acpi=off and quiet and splash were removed from my grub boot entry.

When I just removed splash & quiet it got stock on an apci entry,which I shall get more information on ie a camera screen shot.

i have attached a screen shot of my laptop with the removal of acpi=off from the boot command line, this is as far as my laptop boots to and does not get any further now.

[nullack (nullack)]

Confirmed, thanks for responding Andy

[Andy Rogers (andy-rogers)]

I have replaced acpi=off with noacpitimer and my laptop now starts as expected with wireless & display driver working as expected

[Andy Rogers (andy-rogers)]

Should be noapictimer not noacpitimer

There are some issues with hpet timer and clockevents. Could you try

to verify how this looks for you?

Before I try this Kernel, will this work on my laptop as Iam running amd64 version of Ubuntu? It it won't it there a link to one that would run on the amd64?

Thanks

On Asus F3T and F3M, also boot only with noapictimer parametr....

I have downloaded the amd64 version from http://people.ubuntu.com/~smb/bug254668/linux-image-2.6.27-3-generic_2.6.27-3.3smb5_amd64.deb and it works thanks.

It boots just as I would have expected it would have, however I just had one problem which was my Nvidia display driver which did not compile because the source was not installed.

Good news then, Thanks.

Stefan or anyone

How do I go about installing that image on a machine that will not boot?

[Stefan Bader (smb)]

Try either "noapictimer" or "highres=off nohz=off" on the non-working kernel in order to boot it.

[Andy Rogers (andy-rogers)]

I have downloaded the latest 2.6.27-3 kernel which is pending to be uploaded to the repositeries and for me now this bug has been fixed.

Thanks

Andy

[Stefan Bader (smb)]

I am marking this as fix committed since Intrepid has been rebased to 2.6.27-rc6 which contains all the mentioned fixes.

[feld (felderado)]

I'm affected by this. I have 2.6.27-3 and no more updates are available. What is the reason for this not being fixed on my AMD64 install?

Attached is my hardware info.

[Leann Ogasawara (leannogasawara)]

Setting this to "Fix Released" based on the decision to stick with the 2.6.27 kernel for Intrepid - https://lists.ubuntu.com/archives/kernel-team/2008-September/003107.html

@feld - It would be great if you would open a new bug report. It seems you have different hardware than the original bug reporter and this will likely require a separate fix. Thanks.
