I have "not-G" A315 with 2200u and can boot with acpi=noirq. With lots of warnings, but works, no slowdown. Thought this option does same with irqs as acpi=off or pci=noacpi (using MPTable instead of ACPI table).
I'm still on factory 1.03 BIOS, and with "noapic" parameter everything looks OK on Ubuntu 18.10. Also have idle=halt param to avoid "random soft lockup bug" https://bugzilla.kernel.org/show_bug.cgi?id=196683 I suspect, updating BIOS may bring more problems. So even new AGESA (which may fix lockup bug) is no worth reason for me to update. ** Bug watch added: Linux Kernel Bug Tracker #196683 https://bugzilla.kernel.org/show_bug.cgi?id=196683 -- 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
