Try my kernel, it looks like your kernel is in panic/freeze mode.

To get my kernel, open a terminal on the FOG Server. Login as root or, as you’re using ubuntu, make sure your user has sudo permissions.

To test sudo try:
[code]sudo touch /tmp/someTestFileIAmMakingUp[/code]

It should ask for your password, enter it. If you get no errors, you should be set.

Then cd into the tftpboot/fog/kernel folder.

[code]cd /tftpboot/fog/kernel[/code]

Copy your old kernel just as a backup.
[code]sudo mv bzImage bzImage.orig-29JAN2014[/code]

Then get my kernel and try again:

[code]sudo wget --no-check-certificate https://mastacontrola.com/fogboot/kernel/bzImage[/code]

Hopefully all will work again.

[eddieduce]

I got a ‘unrecognized option’ message for ‘–no-get-certificate’.

[Tom Elliott]

I just updated it, sorry thinking of wget where I wanted a check

[eddieduce]

message ‘failed. Name or service unknown.’

[Tom Elliott]

try prepending with sudo, I updated the code.

The next thing, make sure wget is actually install.
[code]sudo apt-get update
sudo apt-get install wget[/code]

[eddieduce]

‘sudo apt-get update’ failed. with many file not found messages.

‘sudo apt-get install wget’ is updating but is barely on 9%.

Would you recommend just re-installing FOG. This is the production server. The downtime has extended too far now. Would you recommend circling back to .29?

[Tom Elliott]

How did you upgrade your system?

Did you just upgrade or create a new “Fresh” install?

[eddieduce]

Fresh install. What I mean to say is,

is it a FOG .32 issue or more a kernel corruption issue?

The original system is giving problems and I decided to rebuild a new one (the one we are discussing).

[Tom Elliott]

And you’re behind a very slow internet connection?

I don’t have the fastest of upload speeds, but they are 5MB, plenty enough that a normal download of my kernel should take about 5 minutes (max). It’s only just shy of 6 MB

[eddieduce]

no, I am installing wget. …28% at the moment.

Correction, I am updating packages, and it is barely at 42%.

[eddieduce]

The process finished. W-get for the kernel was unable to resolve host address for your site .

[Tom Elliott]

Try again, dns for somereason was lost, fixed now.

[eddieduce]

No go. ‘Name or service not known. Unable to resolve host address <… >’

[Tom Elliott]

Okay, try again.

I had to reboot both of my routers. I was testing multicast and it brought down my network.

[eddieduce]

Still unable to resolve.

[Tom Elliott]

Can you run:

[code]ping mastacontrola.com[/code]

[eddieduce]

I ended up re-installing FOG but OS kept giving other problems extracting files, and connecting to network so, am re-installing server version of Ubuntu 12.04 .

Hi Tom,

I was having a similar issue as was posted here. Got kernel panics trying to register a HP ProDesk 600 G1 SFF.

Using the kernel you posted solved my issue. Thank you so much. Great to find an answer by using the search on the forum.

Cheers,
Tyler Coan

I saw a similar panic to the one originally mentioned in this thread, so I downloaded the kernel that Tom linked. However, now I get a new issue:

[CODE]request_module: runaway loop modprobe binfmt464c
Starting init: /sbin/init exists but couldn’t execute it (error -8)
request_module: runaway loop modprobe binfmt464c
Starting init: /bin/sh exists but couldn’t execute it (error -8)
Kernel panic - not syncing: No working init found. Try passing init= option to kernel[/CODE]

This occurs when trying to perform full host inventory of a Dell Optiplex 3020, with Fog 0.32

[Tom Elliott]

@tsnowtttc

You probably downloaded the 64 bit kernel.

Try the following:
[code]cd /tftpboot/fog/kernel/
mv bzImage bzImage.2014MAR31
wget -O bzImage --no-check-certificate https://mastacontrola.com/fogboot/kernel/bzImage32[/code]
