Getting same problem on AMD Ryzen X18700 with GIGABYTE AB350-GAMING3 motherboard (F5 - latest bios version)
Setting acpi=off gets me into login screen but fails to authenticate me .. so, I`m stuck there. This occured when I tried to upgrade from 16.04 to 16.10 ... then I tried installing the 17.04 with same problems ... instal was hitting the IRQ vector 07 problem. If you guys need any other info, please let me know and I can collect some more. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1671360 Title: System doesn't boot properly on AMD Ryzen / Gigabyte GA-AB350-gaming-3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1671360/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
