Boot – Ubuntu 18.04 Won’t Boot on Dell Inspiron 7375

This is the Ryzen 7 2700u version. Ubuntu 18.04 nor Ubuntu Daily will boot. What can I do? Here's the screen when I boot from Ubuntu 18.04 USB.

I have the Ryzen 2700U Inspiron 7375 as well. I managed to get this working pretty well, however I had to get it installed using Antergos. I wasn't able to get it reliably booting under Ubuntu 18.04 unless I left acpi=off set in the kernel parameters and it wouldn't boot at all to the 4.17 kernel. I started trying different distributions and Antergos worked perfectly the first time (though I may have been lucky since afterwards it seemed 50/50).

After logs of digging and experimenting, I finally found these kernel parameters to be the key (using with linux kernel 4.17.2-1-zen from the Antergos linux-zen package):

amd_iommu=on ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2

Under Antergos I added these to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub then ran

sudo grub-mkconfig -o /boot/grub/grub.cfg

Now things are working pretty well! Maybe these options will help get things working under Ubuntu as well.

update: I just downloaded the 18.04 installer and tried to boot from it again (which comes with the 4.15 kernel). When I added the parameters above (by hitting 'e' on the bootloader) it was able to boot and work correctly. I didn't want to try an install over again so I didn't proceed further, but it appears to work correctly off of the live USB at least.
