 Installer is frozen

I've tried to install Paldo on an IBM ThinkPad T22 (P3-900, 256 MB RAM).
It's from a yesterday downloaded Live-CD.
Partitioning runs properly, copying the install files stops at approx. 150 MB, and the installer is frozen. As an extra gimmick, the gnome-panel crashes. The virtual consoles (Ctrl+Alt+F...) are unavailable.

Is it possible to give any cheatcodes while install (e.g. acpi=off?) to avoid this?

Best regards

Mario

Well, we have only the error-messages in the terminal.
Open a terminal by mouse-right-click "Open in a terminal" and type
Code[In neuem Fenster öffnen]
sudo paldo-installer


If it stops you might see an error message.
btw. what kind of branch of the live cd did you load?

Latest stable build is:

Build Date: 2008-11-19 04:09 GMT

and testing is:

If stable branch has any error you can also use the Boot CD and do the Old school install

Just tested the last live-cd of testing branch in VirtualBox. It freezes in the squashfs copy state at 5% in keyboard layout uk and de I've tested:





I'll test now the latest stable live cd the same way ...

I can conform that our actual stable live cd is BROKEN!



After around 5 % of squashfs-step the gnome-panel disappears and everything freezes on my virtual machine. Might be the kernel or squashfs itself. The actual kernel 2.6.27.7 might help to fix this issue. Seems only the old school install with the boot cd is atm the only way until we fix the issue.
This delays the release of 1.16 ...

In your data you wrote you've 256 MB. My old images working with that. In the new images unsquashfs uses parallel unpacking what need a lot of memory. It works if you have a pc with 1 GB ram in it. Well we are now at the run to tweak unsquashfs to use less memory. Here some out of our chat:

<juergbi> amnon: with how much memory in the vm have you tested the installation?
<amnon> wait a sec
<amnon> 256 MB but I'll pop it up with 512 MB and test it again. I've 889 MB here I'll give you the stand in couple of sec
<juergbi> installation went fine on a 1GB vm here
<juergbi> unsquashfs seems to need quite a lot of memory
<amnon> hmm seems so. I'll run 512 now
<amnon> with 512 I'm over the 5% now let's see
<amnon> at 20 % gnome-panel went of ...
<amnon> froze at 419.O MB
<juergbi> hm, i'd have expected that unsquashfs works with a lot less memory
<amnon> I ran 512 with 8 of it for video
<amnon> now I'll try testing iso
<amnon> my old image of 19.08.08 I gave to linuxuser still installs with 256 MB
<juergbi> amnon: yes, i have an idea what might be the issue
<juergbi> amnon: squashfs 3.4 has introduced parallel unpacking which should improve performance but will require more memory
<juergbi> i'll try to lower the memory requirement
<amnon> I noticed that cos it writes parallel using one cpu
<amnon> well in testing tis the same went of at 420.6 mb

<juergbi> amnon: update committed to fix installation issue and update kernel to 2.6.27.7

hope the next build of the live-cd images will help you. I'll also test them on my virtual machine in VirtualBox.

Thanks for your answers. Unfortunately, I don't have a CD burner,
that's why I have to ask my friends for help burning an alternative image.

But should the installer on my downloaded CD with activated swap? I have a swap partition with 1 GB, is this enough? Or is the installer completely broken?

The issue was squashfs. We managed to support 256 MB Systems again. The installer wasn't broken at all. Only the arrangement of packages broke the livecd. If you have a 1 GB-Ram on your machine you can still install the actual image. I've only 886 MB on my tv-pc so even I can't install the image. The next image will be up soon and I'll give you my comments on it. My old image I created for a german magazin called Linux User has the old squashfs on it, which didn't do the trouble we have now. So be patient and we will see if the problem is solved.

<archive name="squashfs$VERSION">
<!-- reduce memory requirements of unsquashfs to support installation on systems with 256 MB RAM -->
<cmd>sed -i -e 's/BUFFER_DEFAULT [0-9]*/BUFFER_DEFAULT 32/' squashfs-tools/unsquashfs.c</cmd>


Thx again for pointing us into the right direction. We've so much to do before the next rls 1.16 is out and we don't use "old" machines like your laptop anymore, but it is good to having you.
