Stuck at loading initial ramdisk message

[Tibby709]

After rebooting my computer to update iommu on, it won't boot past loading initial ramdisk. I've tried to change the iommu back to off and nothing.

i5-6600k, 16gb ram, single boot drive nvme and 4 drives in raid10

I have the same issue

the fix was to boot using the rescue option from the installation usb
then edit

/etc/default/grub

and change

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt video=vesafb:off video=efifb:off"

with

GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on iommu=pt video=vesafb:on"

also make sure there is a timeout on the grub boot menu
GRUB_TIMEOUT=5

save and then run update-grub

update-grub

reboot and it should work


in case the initrd image is damaged you can rebuild with this command :

mkinitramfs -o /boot/initrd.img-$(uname -r)

and run again update-grub
