# After install, it was necessary to boot with USB and chroot (https://www.techzim.co.zw/2021/01/how-to-restore-ubuntus-efi-partition-in-ubuntu-20-04/):

sudo fcsk /dev/nvme0n1p2

sudo mount /dev/nvme0n1p2 /mnt
sudo mount /dev/sda1 /mnt/boot/efi
or i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt

echo "Append GRUB_CMDLINE_LINUX with nvme_core.default_ps_max_latency_us=0"
nano /etc/default/grub
echo "Reboot machine"

# Reboot

echo "Verify changes are active: cat should return 0."
