Hi. Thanks for your precious informations. I start with noapic and there is the lspci output : https://paste.ubuntu.com/p/jm8MBy4qND/
Obviously I can see the same values as you for iommu (0:00.2)... So I'll try to reboot again with "ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2" instead of "quiet splash". -- 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
