Hi Adam, Thanks for your answer. We are waiting the patches.
Best Regards Richard Yang, Adam <*> 2019. 04. 05., P, 17:04 Hi all, We're still currently verifying the patches (not one patch but a lot) so please be patient and be careful about your upgrades from old working kernel (which we are so sorry for the inconvenience). I'll comment and change status about related issues if the patches are merged and *released* as upgrades. Thanks for your patience. -- Software Engineer, MLSE AMD, Advanced Micro Devices Phone: * Adam Yang From: [email protected] <[email protected]> on behalf of Richard Baka <*> Sent: Saturday, April 6, 2019 12:52:52 AM To: Yang, Adam Subject: Acer notebook firmware issue Dear Adam, Regarding this bug: https://bugs.launchpad.net/bugs/1776563 I would like to ask you where/how will the released fix be appeared. Is there any kernel commit or we should wait for the manufacturer's reaction? Thanks, -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in 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 Status in amd: Fix Released Status in Linux: Incomplete Status in linux package in Ubuntu: Triaged Bug description: CPU: Ryzen 5 2500U VGA: Radeon 535 Notebook: Acer Aspire A315 This is a brand new notebook on the market with Ryzen 5/Radeon. The default kernel of Ubuntu(18.04) hangs at loading with message: tsc: Refined TSC clocksource calibration: 1996.250 MHz clocksource: tsc: mask: 0xffffffffffffffff max_cycles: (...), max_idle_ns: (...) Soft lockup Using pci=noacpi kernel parameter kernel loads without any problem but my notebook produces more heat than on Win10. If I know right Acer notebooks need ACPI to the correct power management. The same thing happens on mainline 4.17,4.18rc1-2. BIOS upgrade to the latest version: 1.08 hasn't helped This problem has been reported upstream: https://bugzilla.kernel.org/show_bug.cgi?id=200087 The latest correctly working kernel was 4.13.* but the heat problem was present with this too.
