I have exactly the same problem with a Gigabyte AB350-Gaming 3 motherboard and a Ryzen 1800+.
- Ubuntu variations (Ubuntu, Neon, Kubuntu, Budgie) and openSUSE do not work out of the box. They stall with a bunch of 'irq trap at vector 07' messages. - For all of these, after adding acpi=off to the kernel parameters, it runs/installs, but runs on only one core. The system locks up when you try to shutdown. - I tried other acpi parameters but nothing seems to make a difference. Only acpi=off has an effect. - Fedora and KaOSx run and install with no obvious problem. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
