Public bug reported:
Ubuntu is unable to boot from the installation USB on a Dell Inspiron 7375,
with a Ryzen CPU. This affects Ubuntu 19.10 (latest daily), 19.04 and 18.04.2
(videos of each unsuccessful boot will be attached).
I was able to boot using a workaround, by adding to the kernel line:
amd_iommu=on ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
You can see it here:
https://askubuntu.com/questions/1036357/ubuntu-18-04-wont-boot-on-dell-
inspiron-7375
I used this workaround to run the apport-bug tool.
The problem should be in an ubuntu specific vendor patch or configuration since
I was able to boot successfully in:
* CentOS 7 (kernel 3.10)
* OpenSUSE Leap 15.1 (kernel 4.12.14)
* OpenSUSE tumbleweed (kernel 5.1.16)
* Fedora 30 (kernel 5.0.9)
* Manjaro (kernel 4.19)
* SystemRescueCd (kernel 4.19.34)
