You could have pointed your DHCP server (option 67) to undionly.kpxe as well instead of renaming…

Would be actually a good idea because we often ask “Which iPXE file you use?” when people have issues. If you tell us pxelinux.0 (although it’s actually undionly.kpxe) that might cause a lot of confusion…

@JDoornhof Coming from FOG 0.32 I guess you were using pxelinux(.0) as a boot file. FOG 1.2.0 and FOG trunk use iPXE instead of pxelinux and we have seen the exact same issue that you have chainloading from pxelinux: https://forums.fogproject.org/topic/5642/end-kernel-panic-not-syncing

Wow! Thank you soo much!

sudo mv /tftpboot/pxelinux.0 /tftpboot/pxelinux.0.OLD1
sudo mv /tftpboot/undionly.kpxe /tftpboot/pxelinux.0

That fixed the problem for me, it actually failed to chainload.
Strangely ln -s did not work, just renaming it did it for me.

I would start by re-running the trunk installer script. No need to use svn or git since you have a pretty new install, just run the installer again.

Then navigate to /var/www/html/fog/service/ipxe (you may need to adjust the path for Ubuntu) make sure the inits and bzImages are there. There should be two sets one for x64 and one for x86. maybe just do a ls -la on that folder and post the results here. The installer script should verify they are the right once since the installer is checking image fingerprints now to ensure things are as they should be.

We had this issue a while a go and has been resolved for a 1000 or so revisions.

Lets find out a bit more about the target computer.

What is the make and model?
Is it configured for efi or bios mode?
iPXE is not and issue since you are getting the FOS kernel to start (kind of).

Since you make references to kernels and you are running the trunk version of fog. I would just run through the ./installfog.sh script again and get the correct kernels and inits installed. Lets not make some bad decisions based on what we think is installed.

Target pc’s/laptops:
I tested with;
Gigabyte Brix 4010
Gigabyte Brix 5010
Lenovo B50-B80
(used 2 of them all, just to be sure)

Bios of the clients is configured to use legacy mode.
iPXE works fine untill the execution of a task.
I installed everything as bare as possible (even tried 2 clean installs, Ubuntu+LAMP+FOG via svn checkout)

What the error is saying is that the kernel can’t find the inits (virtual hard drove) for the FOS client.

This makes more sense now, thanks in advance!

What did you upgrade from?

I went with a clean install on this machine.
We used to run ubuntu 12.04 + fog 0.32

Hi,

Today we are upgrading to ubuntu 14.04.4 + FOG 1.2.0 (Version: 7100)
Installing went all fine, but i got stuck when I wanted to register a computer.

I Already tried different kernels, without succes.
The machine/server Fog is running on is a HP Proliant ML350 G5
