I don't know if it is the same problem, but the Lenovo notebooks Lenovo E585 and Lenovo E485 with Ryzen 5 2500U or Ryzen 7 2700U also do not boot on Linux. This is very frustrating, because you have to add command lines to GRUB make them even able to boot on Linux:
ivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1 and spec_store_bypass_disable=on or spec_store_bypass_disable=seccomp Otherwise Linux does not boot. Thanks to evilazrael who found that workaround, otherwise still no-one would be able to boot a Linux distribution on the laptop. The initial analysis from him you find here: https://evilazrael.de/node/401 An ongoing discussion of the case you find here: https://forums.lenovo.com/t5/ThinkPad-11e-Windows-13-E-and/ThinkPad-E485-E585-Firmware-bug-ACPI-IVRS-table/m-p/4191484 It would be nice if it would be fixed, because many user will relinquish using Linux if it does not boot on the first time, and also all others users need a fix, because the workaround may reduces performance and increases power use. -- 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
