Fog wont load past kernal_thread_helper+0x6/0x10

[viper02]

I just recently updated my fog from 0.32 to 0.33b and I am unfortunately still stuck when I try to upload the image from an hp pro-book 450G1. I’ve tried registering both through a quick register and manually by inputting the mac address selecting the image and uploading. Both seem to stop at the 5.731830 kernel_thread_helper.

Are you sure you’re using the correct bzImage and init.xz pair? A 32 bit bzImage needs the 32 bit init_32.xz file. A 64 bit bzImage needs the 64 bit kernel.

As you say you’ve upgraded the fog system (I would typically recommend a fresh install) you likely need to adjust the values in FOG Configuration ( ? ) icon -> FOG Settings -> TFTP Server

Make the following changes to the relevant lines:

FOG_TFTP_PXE_KERNEL = bzImage (Exactly, NOT fog/kernel/bzImage)
FOG_TFTP_PXE_KERNEL_32 = bzImage32 (Should already be set)
If using Debian variant (e.g. Ubuntu, Debian, mint):
FOG_TFTP_PXE_KERNEL_DIR = /var/www/fog/service/ipxe/
If using Redhat Variant (e.g. Redhat, Fedora, CentOS, Scientific Linux)
FOG_TFTP_PXE_KERNEL_DIR = /var/www/html/fog/service/ipxe/
FOG_PXE_BOOT_IMAGE = init.xz (Exactly, NOT fog/images/init.gz)
FOG_PXE_BOOT_IMAGE_32 = init_32.xz

[viper02]

Ok made the setting changes to the tftp but i am still running into the issue. The G1 is a gen4 i5 processor the first one where we started having issues. Should i make the change to a 64bit kernel instead of a 32? if so how do i go about making this change if necessary

[Tom Elliott]

When you changed over, are you booting to undionly.kpxe or pxelinux.0?

You need to update (from 0.32 to 0.33 upgrade) the option 67 to point to undionly.kpxe rather than pxelinux.0.

Ok i managed to botch something up i was attempting to make sure i had the correct kernel but doing the kernel update from the fog config. Afterwards when i try to create a image on a client i get bad kernel. So i went back to the kernel updater but i noticed that the unpublished is no longer loading on the page. I going to attempt to re-run the last good kernel and then once i’m back up check the dhcp server./

[Tom Elliott]

My server is down at the moment, due to a kernel panic on my storage server, so I expect it to be down until around 5 pm EDT.

[viper02]

ok is that why it gets stuck at moving file to tftp server

[viper02]

Ok so i downloaded the kernel earlier from the site is there anyway to copy it to the folder and replace the other kernel? i’ve tried doing it with a click and drag which give me a permission denied.

[BPSTravis]

Open a terminal and type in sudo nautilus

That will give you a GUI with copy permissions after entering your password.

otherwise use the copy command

cd /var/www/fog/service/ipxe
mv bzImage bzImage.orig.4-15-2014

cp /location/of/your/downloaded/file / /var/www/fog/service/ipxe

[viper02]

ok the one i downloaded was named tom.elliot i need to change the name to bzImage first correct?

[BPSTravis]

Yes, it needs to be named bzImage

[viper02]

Ok used nautilus to change the downloaded tom.elliot.32 to bzImage and copied that file to var/www/fog/service/ipxe renamed the original to bzImage<date> and thats that. however when i attempt an image i am still getting bad kernel image. Do i need to reboot? sorry def noob at this

[BPSTravis]

Do you have a specific kernel set under the FOG UI for that host??

Also a recheck of what Tom posted above:

[QUOTE]Are you sure you’re using the correct bzImage and init.xz pair? A 32 bit bzImage needs the 32 bit init_32.xz file. A 64 bit bzImage needs the 64 bit kernel.

FOG_PXE_BOOT_IMAGE_32 = init_32.xz [/QUOTE]

[viper02]

I have the init_32.xzfile and i made the changes specified above. I errored by trying to update the kernel from the updater page. the part im at now is should i name the kernel bzImage or bzImage32? this is with the copy and paste method and if i’m not mistaking it has to go to the ipxe folder correct?

[BPSTravis]

That depends on which kernel that tom.elliot is.

If it’s 32 bit then it needs to be bzImage32.

[BPSTravis]

Just download both kernels from here, keep them named as they show and copy them to the ipxe directory.

ok so i am now able to register it and inventory… the last thing i will need assistance with is this. I set a task to upload an image but when the client pxe boots it doesn’t see it and goes to the fog load page. What am i missing?

[BPSTravis]

Can you include a screen shot of the task you created?

Are you sure you created a task for the correct host?

Did you get any errors when creating the task?

[viper02]

Screenshot after task

[viper02]

no errors popped up and yes its the only one like it listed in my inventory. I was able to get it there using the quick inventory function
