I'm currently have the exact same issue with my AN515-42-R5GT Acer Nitro 5 Ryzen 2500U + RX560X.
Adding: ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 iommu=pt Seemed to help me out on 4.19rc2, but 4.18.10 requires noapic on Sabayon Linux. Tell me whatever you need an I'll pull it all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776563 Title: Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs, can't load, kernel freeze (AMD Ryzen 5/Radeon/Raven) / AMDGPU Hybrid crash To manage notifications about this bug go to: https://bugs.launchpad.net/amd/+bug/1776563/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
