Stuck at loading initial ramdisk message

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


and change

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


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

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

save and then run update-grub


Generating grub configuration file ...
Found linux image: /boot/vmlinuz-5.13.19-2-pve
Found initrd image: /boot/initrd.img-5.13.19-2-pve
Found memtest86+ image: /boot/memtest86+.bin
Found memtest86+ multiboot image: /boot/memtest86+_multiboot.bin
Adding boot menu entry for EFI firmware configuration

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
