@mckayj @Quazz Great this has turned out to fix the issues on those CPUs. Thanks heaps!! Will add x2apic to the official FOG kernel build. Let’s hope this is not going to cause any trouble for other devices. ;-) Edit: Added the option, will be in the official binaries soon: https://github.com/FOGProject/fos/commit/34967bf3f42fe56d835e1e179cdea78213ab3b6b

@Fritch94 I ran into this exact problem after upgrading FOG to the latest svn. It took me a while to track it down, but this solution worked: https://forums.fogproject.org/topic/3433/unable-to-upload-first-image/5 It was a suggestion Tom made a while ago to another user with similar issues. Replacing pxelinux.0 with a sym-link to ipxe.kpxe did the trick for me. Hopefully it will work in your case.
