Fedora 29 really do not show any errors? On 28 there was two lines in dmesg "ioapic[4] not in ivrs table" which present on screenshot attachment for this bugreport. And third line was like "switching irq routing to physical flat" - sorry, i'm not remember exactly... I did not find anything useful about this "physical flat" irq mapping mode. But seems this is similar to noapic. -- 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
