Mine device (a315-41-R19S) can sleep on Ububtu 18.04 LTS with default kernel 4.15. But it have no dGPU - maybe this is the reason...

Fedora 29 really do not show any errors? On 28 there was two lines in dmesg "ioapic[4] not in ivrs table" which present on screenshot attachment for this bugreport. And third line was like "switching irq routing to physical flat" - sorry, i'm not remember exactly... I did not find anything useful about this "physical flat" irq mapping mode. But seems this is similar to noapic. -- 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

Are these (other than noapic) workarounds really enable APIC controller? With acpi=noirq only PIC and MSI entries present in /proc/interrupts. So I assume acpi=off does the same. While noapic obviously disables APIC but works fine for me. Looks like ivrs_ioapic... enables APIC, but in my case system is very slow and even not always boots. Is disabled APIC have significant drawbacks (while most of devices placed on MSI-routed PCI lanes)? -- 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

Released 3rd generation of ZEN and this strange thing still persist. So "No fix planned" was not a lie... Kernel parameter idle=halt fixed my problem for R3 2200u (no lockups for 7 months).

[Bug 1690085]
I have random freezes with Ryzen 2200u laptop. Display image just freezes and system stops responding. Only way to get out from this state is to holding power button (even magic SysRq key does not work). No any clues in logs. With Ubuntu 18.04 it was happen nearly once per week (not intense use). After installing 18.10 things become more stable - I've got first lockup after 6 weeks and another after 3. Hangs are completely random and on different cpu load - once I've got this while gaming (and ambient noise continue playing...) I've tried idle=nomwait but this did not help on 18.04 - and line "monitor-mwait will be used for idle loop" was still present in dmesg with this parameter! idle=halt parameter completely disables mwait instruction in kernel and also forces use of only C1 state. In my laptop it does not cause higher battery drain or any suspend-resume issues. But I've not tested it completely an used it for few days... So this may be even not the solution for my problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690085 Title: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1690085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

(In reply to Bráulio Bhavamitra from comment #464) > You freeze seems GPU related, try a new kernel/firmware I also have got amdgpu crash with same screen freeze, but magic key had worked that time and error left in kernel log. And I was able reproduce that with certain game in dolphin emulator. My random freezes happened without any special program running, sometimes in clear gnome-shell desktop.

I assume there is several (at least two) similar problems that cause spontaneous system hangs. One of them is mwait bug listed in AMD errata. Looks like idle=halt is partial workaround for this. But, as said in AMD community forum, guest OS in virtual machine may execute mait instruction and provoke this bug. Luckily, mwait is not common for user-space applications (still not sure about that). Another is power supply problem. This may be caused by unsupported PSU (no 0A 12V) or unsuitable power subsystem on motherboard. This may be partially (again!) solved by BIOS "typical current idle" option or disabling C6 states by .py script. IMO this bios option may be implemented not properly in some mobos firmware. Looks like it only "says to OS" do not use C-states, but does not prevent deep sleep on hw level. Here we got [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) in dmesg and problem persists. Have read some forums with assures of completely stable Ryzen systems work under Linux without any tweks. So not really too many systems affected by mwait and PSU lockups. I think some combination of factors may provoke this behavior. Mobo+PSU, memory latency (why not?) or some vendor-provided bios config. Also in some cases these two problems may appear together. Obviously, segfaults or amdgpu crashes is not related to this bug.

Whoa, looks like ACER really trying fix this! Sadly, current solution is not working for all. And touchpad behaviors somewhat strange.

So if you got message with "typical current idle" option: [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) it means probe of this C-state failed and it must be avoided by kernel. Is there any difference between C-state list in OS with and without this option? I have only laptop with very limited BIOS and can't check. And there only C0-1-2. What about C6? What says zenstates.py about that? Frankly, I have not tried this script - do not want disable power-saving features for laptop. Also some overclocking may solve this problem (see comment 103). Turn on "performance bias" or similar option in BIOS for testing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690085 Title: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1690085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

(In reply to alfie from comment #561) > This is pretty strange, could someone explain it to me? Wasn't mwait bugged > in ryzen? Looks like this patch makes kernel to ignore BIOS messages about unsupported C-state. this function used in "acpi_processor_ffh_cstate_probe" which further used in "processor_idle.c" file. It cause "cx.entry_method" value change from ACPI_CSTATE_SYSTEMIO to ACPI_CSTATE_FFH. It is really strange that this patch works but idle=halt is not. Maybe this is somehow silently disables C6 state. Can your system reach turbo frequencies with this patch?
