the solution ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 iommu=pt isn't helping me on 4.18 or 4.19. I think the first time I got past the CPU stuck issue with this was a fluke.
I now have to boot with the noapic option every time or I get "CPU stuck" over and over. Any and all assistance would be greatly appreciated. ** Attachment added: "dmesg,lspci,journal" https://bugs.launchpad.net/amd/+bug/1776563/+attachment/5196245/+files/AcerNitro5.log -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
