FAI aborting installation on nvme device

[Thoralf Schulze]

Hi there -

while trying to install Debian on a Dell Latitude 7440, FAI aborts with 
"Error in task partition. Code: 710".

format.log on the target host states "No disks defined in $disklist" on 
the first line, which is corroborated by "disklist=" in variables.log . 
The FAI configuration is pretty standard, with only slight changes to 
disk_config.

The block device on the target host - which is a nvme disk - is being 
recognised by the kernel, /proc/partitions and lsblk list existing 
partitions. According to dmesg, these partitions are being picked up 
rather early in the boot process, so missing / delayed loaded kernel 
modules don't seem to cause the issue.

I am quoting relevant lines from fai.log below - please let me know if 
there is anything I can do to further debug this issue.

Thank you very much & with kind regards,
Thoralf.
