Dear Ubuntu Maintainers, here is the summary:
1. Kernel freeze can be resolved by using the mentioned kernel parameters: > ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 It would be the best if the broken DSTD tables were fixed but I think nobody will do it. The workaround with the parameters seems to be a correct solution. 2. For the amdgpu crash there is a patch what works correctly. It will be merged to the upstream after testing. https://bugzilla.kernel.org/show_bug.cgi?id=200517 Patch: https://bugzilla.kernel.org/attachment.cgi?id=277375&action=diff&collapsed=&headers=1&format=raw ** Summary changed: - Acer Aspire A315 ACPI failure on Ubuntu 18.04, kernel hangs, can't load, kernel freeze (AMD Ryzen 5/Radeon/Raven) + Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs, can't load, kernel freeze (AMD Ryzen 5/Radeon/Raven) / AMDGPU Hybrid crash ** Bug watch added: Linux Kernel Bug Tracker #200517 https://bugzilla.kernel.org/show_bug.cgi?id=200517 -- 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
