Ubuntu freezes on load and caps lock flashes

Asked by Shea Barton

ubuntu freezes when it is almost to 3 bars of loading indicator. caps lock flashes after it freezes, and hard drive activity light shows no activity. This happens when booting off the livecd tryout mode, or the normal install option with the cd. ubuntu installed fine through the alternate install disc (text only), but the first time it booted, same problem.

ive used like 4 different cds from different mirrors, burned on different computers with lowest burn speed to the same result. the cd is not faulty.

tried booting text only through the "recovery" mode, or by removing "quiet" and "splash" from boot options, but it feezes and results in the error: Kernel Panic - not syncing: Aiee, killing interrupt handler!

i have run the built in memtest in the bios which passed, but when i ran the ubuntu memtest it churned along steadily and after 13 hours was only to 7% (is this normal?). i don't have the patience to leave my laptop on for a week..

from online forum searches i tried the adding the options "noapic" "acpi=off" and "nolapic" to the boot parameters, but did not help

i installed openSUSE on this machine, and it froze too, unless i selected the "safe kernel mode" from the install dvd, after which in went fine.

thanks,

i am running:
presario cq50-110us
3 gigs ram
nvidia 8100m gpu
hardy hardin 8.04 (not exactly "running" yet)

it must be a incompatibility problem between your processor and the generic kernel which is used by default. If you can install ubuntu through the alternate cd install it and then change the kernel to a compatible version.
However, if you are using the 32-bit version install the 64-bit version. I think it will solve your problem.

no.. im using the 64 bit disc with a 64 bit processer..

i will try using the alternate install disc and selecting a different kernel, but I didn't exactly see the kernel selection option last time I used it.

Please tell have you already tried to install the Ubuntu 8.04.1 standard 32bits...?

Download the standard Ubuntu 8.04.1 32 bits iso image from here:
http://releases.ubuntu.com/releases/8.04.1/ubuntu-8.04.1-desktop-i386.iso
or better using a torrent file:
http://releases.ubuntu.com/releases/8.04.1/ubuntu-8.04.1-desktop-i386.iso.torrent

- Please check the md5sum of your downloaded Ubuntu .iso image file, here the https://help.ubuntu.com/community/HowToMD5SUM howto, and compare with http://releases.ubuntu.com/8.04.1/MD5SUMS

- Burn it on a cd rom, be sure to burn your cd at lower speed you can do usually 4x here an howto https://help.ubuntu.com/community/BurningIsoHowto

Thank you

i guess this kinda solved my problem "ubuntu isn't loading" but only if i use the 32 bit cd, which i don't want, so im closing this and starting a new thread with a more accurate title:

Get the minimal install image and burn it. That is the only one that works reliably for me. It will detect your hardware and retrieve drivers specific to your hardware.

@bart

Going to DC this weekend so it will take me like a week before I try it--But I have a good feeling about this. Thanks
