Grub and nvme disk issue

[Benoit]

Hi Grub :)

I use Grub for almost 10 years and I am in a situation where I am unable 
to make it work on my brand new laptop :(
The laptop has a nvme disk and I read it could be the issue...
Grub version is : grub 1:2.02.beta3-1
OS: Parabola (Arch Linux based)

I am doing :
nano /etc/mkinitcpio.conf
MODULES="nvme"

HOOKS="base udev autodetect modconf block keymap keyboard encrypt 
filesystems fsck"

/etc/default/grub
GRUB_CMDLINE_LINUX="cryptdevice=/dev/nvme0n1p2:nvme0n1p2_decrypted"
GRUB_ENABLE_CRYPTODISK=y

mkdir /boot/grub
grub-mkconfig -o /boot/grub/grub.cfg
grub-install --target=x86_64-efi --efi-directory=/boot/efi 
--bootloader-id=Parabola --recheck /dev/nvme0n1p1
mkinitcpio -p linux-libre

(I am trying to use Grub with a full encryption disk, but I am almost 
sure it is not the issue as doing exactly the same on another computer 
is working perfectly...)

When I restart the computer after the Grub installation I can see the 
new entries in the UEFI list in my BIOS but it makes a black screen and 
immediately jumping into another entries which is a system recovery type 
of thing...

Any idea what would be wrong ? I know systemd-boot is working and I have 
been able to see the list but I would like to stay with Grub as I like 
it and particularly the fact I can use a full encrypted disk with /boot 
included...

Many thanks

Belette
