Ubuntu 19.04 on Ryzen 2500u

Hello Level1

Looks like the watchdog cpu softlock issue is still occurring on Ryzen 5 2500u

The system is the Acer Nitro 5. Not sure if this is a bios error or OS issue, but could never get Ubuntu to boot without the using nopci boot flags.

Praise the penguin ma dudes

I had to add:

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

to get my 2700u booting on anything except Fedora or Antergos. And the version of Antergos I used at the time had a bug that wouldn’t install GRUB.

Linux on Ryzen laptops is fun.
