Thanks 
Here is the stock Kernel 4.19.4 with the TomElliott .config file and the CONFIG_VMD set to Yes. The FOG patches are not included (this is the stock kernel)

For those who wants to try quickly & report problems is there is any left.
I suppose it should resolve

Hi,
after more than 60 kernel compilations, i found the faulty kernel config option :
Please activate CONFIG_VMD=y
Bus Options -> PCI Controller Driver -> Intel Volume Management Device Driver
@Sebastian-Roth Thanks for the link, i was looking for the fog .config and patches in the repos !
I’ll start by compiling the stock fedora kernel from src-rpm (including fedora patches) to get a valid build system, then to compile a stock kernel with the fedora .config then the one from TomElliott with fog patches and see what happens at each step. I’ll try to get back here before end of the day !
Hi everybody,
My company own one of these too. Same problem with fog which fail on nvme disk not found.
I just installed Fedora 29 which works correctly on it (i’m currently writing with it), i will try to compile a kernel with the fog config to add to my grub configuration and see what happens with the F29 userlands. Years i didn’t compiled a kernel, hope to do it quick ;).
If there is anything you want me to do, ask me, i will keep the computer with me until a solution is found, and can do whatever needed to help resolve this issue.
