I am having troubling booting from Fog on my HP DC 7800. Yes they are old. But they were working on an older version on FOG 1.5.2 or ealier I am not sure. I am currently running 1.5.5. I read other posts about changing the kernel to 4.15.2 and adding the acpi=no in the kernel option. I have tried this and it says kernel is too old. When I try a newer kernel and the latest it says RCU grace-period kthred stack dump. Thank you.
@browolf Are you running into the CPU stall issue too?

Having this exact problem after having to rebuild our fog server from scratch. Have 100s of DC7800 and am having to resort to imaging them one at a time with clonezilla instead :’(
Our original fog server which worked fine was corrupted by Vmware and I didn’t have a backup.

Yes -> https://fogproject.org/binaries1.5.2.zip ->
This is why you are one of the FOG Project Digital GODS.
@mclapper68 Depending on your deployment volume. You could download and extract the zip file. Save the init.xz as init152.xz and move it to /var/www/html/fog/service/ipxe on the fog server. Then finally update the init field for this host to init152.xz and for the kernel do the same, rename bzImage from the zip to bzImage152 and move to the same location then update the kernel field for this host to bzImage152. (sorry for the disjointed post I was thinking linearly here). That workaround will allow you to continue to use fog as it was deigned for the new kit, and still support his older stuff without fear of an update breaking your older systems.
is there a place to download the 1.5.2 inits? I only know how to download the current release
Yes -> https://fogproject.org/binaries1.5.2.zip -> extract and find the original inits and kernel binaries
The kernel panic sync issue is that the inits and the kernel do not match. You can’t move to a previous release kernel where the inits are expecting something newer.
For your kernel parameter shouldn’t it be
acpi=offno might be a synonym, but I think I would try it as off. https://www.kernel.org/doc/Documentation/admin-guide/kernel-parameters.txt
Its also strange that a newer kernel would do this. How many of these older systems do you have in your environment?
@Developers is there a place to download the 1.5.2 inits? I only know how to download the current release.
