Best practice if a kernel will not boot a system?

[Matt.Collins]

There are multiple kernels available for download. I would suggest taking a look at the list of working devices ([url]http://www.fogproject.org/wiki/index.php/WorkingDevices[/url]) many of which have notes on the models of which kernels work. If they aren’t working and are not listed, you’ll have to do some testing. In my district when working with kernel testing, I was sure to rename the kernel to identify which model I was testing it on as bzImage is the standard name and will overwrite your existing kernel unless you specify otherwise.

If I recall, you can manually add a host by MAC and also set the kernel and arguments from the host settings page.

Hope this helps.

Hi,

thank you for your answer.
Means i can place many kernels in the kernel directory for example bzImage_3.8.8
Do you refernce the full path to kernel or just the filename?

The Systems not working are pretty new, my mind tells me that older kernels cannot
give any success?

Lets say i cannot get it to work with any available kernel i need to cook one myself as last straw?!
I’ll try to post some screenhots (errors) of the non working systems.

I know that KS are Kitchensink kernels but what are PS Kernels?

You can have multiple kernels installed on your system, however you need to add the kernel location to the host. For example fog/kernel/kernel name would be what I would input under the host settings.

If you don’t find a kernel that works with your machines, you’ll have to compile your own, which is out of my league. Perhaps someone with a bit more knowledge on building kernels can step in here.

Hi,

thanks again… well i will figure that out and report back…
Lets build a kernel K+E+R+N+E+L childsplay hehe [I]*joking[/I]

I’m at a loss because NONE of the Kernels will boot our new Lenovo E420 laptops. Still have MDT I can revert to for one offs but this will be difficult when having to do an entire lab.

If no kernel works:

• Take the HDD out of the machine, that can’t boot FOG
• Put it in a machine, that can boot FOG
• Assign the right image to that machine
• Choose “Shutdown after task completion” in task configuration
• Start task
• After task is finished, put the HDD back in the original machine
• Start the machine

This is a workaround, if you have generalized images (Sysprep for Windows).

Good work around for our one offs! Thanks!

but only in case of deploy, i mainly will use fog to backup, i cannot go to each not booting machine the backup manually.
Seems i really have to cook a kernel myself argh!

have you ever tried a self made kernel? Iam actually testing with kernel sources of 2.6.39.4 and 3.9.2

If you need help making a custom kernel, just keep up with what you’ve done, post your questions, and we’ll help as best we can. It appears daunting, but after you run through it a few times on a VM, it’s gets simple.

actually it’s doing fine i have succesfully compiled two kernels but i cannot test them at home, iam back at work next week on tuesday. [url]http://fogproject.org/wiki/index.php?title=Building_a_Custom_Kernel[/url]

Will the latest 3x kernel work with fog? is it true that the april kernel 3.8.8 is then a 3.8.8x kernel?

Hi,

@Dustin would you like to test a kernel i compiled with latest kernel sources 3.9.2?

Greetz X23

Hi,

i compiled my own kernel 3.9.2-4 and two of the machines work now instead that one tells me now hdd not found instead of kernel panic but this is only one missing driver.
