[Kernel-packages] [Bug 1747463] Re: kernel crashes during boot unless IOMMU is disabled on Ryzen 1800X
I have the same issue, but with a Ryzen 7 1700 with the following setups: Setup 1: Motherboard: Gigabyte B450 Aorus M (Latest BIOS installed) RAM: 32 GB DDR4 Crucial 3000 Mhz GPU1: Sapphire Radeon RX 580 Nitro+ Special Edition 8GB GDDR5 GPU2: Asus Mining Radeon RX 470 4G GDDR5 SSD: 240 GB WD Green Setup 2: Motherboard: ASRock AB350M Pro4 (Latest BIOS installed) RAM: 32 GB DDR4 Crucial 3000 Mhz GPU1: Sapphire Radeon RX 580 Nitro+ Special Edition 8GB GDDR5 GPU2: Sapphire Radeon RX 550 2G GDDR5 SSD: 240 GB WD Green The issue first started after installing the second GPU on each of the systems. I can't even boot the system, as the errors appear right after BIOS initialization. The errors are like: [exerpt] AMD-Vi: Completion-Wait loop timed out AMD-Vi: Completion-Wait loop timed out AMD-Vi: Completion-Wait loop timed out ...

After some research I discovered that it is a IOMMU issue. I turned IOMMU off on both motherboards, and I managed to boot the system. I am an architect and I use blender for GPU rendering (this is the idea of having two), but the AMDGPU-Pro driver from the AMD's website (the only one that Blender uses for GPU rendering, as it can't use the open one) affects the way Gnome works on Xorg. It affects in the way that it doesn't start at all, it keeps restarting to the GDM screen... Any ideas?

Installed is Debian Stretch/Sid with kernel 4.9.6. Successful boot without crash is possible with - disabled amdgpu (e.g. old nomodeset) - or disabled iommu (iommu=off) otherwise the kernel crashes and the file-system is corrupted. iommu=off is much better way now, because the notebook runs in energy efficient manner - the fan is quiet or stopped.

What about bug in the amd_iommu? I think this because I tried to switch off external GPU using acpi_call module. The following command was successful: echo '\_SB_.PCI0.VGA.PX02' > /proc/acpi/call while running kernel with no KMS (no amdgpu). Fan really went silent after this, but kernel crashed in several seconds in similar way like with amdgpu and active iommu. The filesystem is after every crash corrupted. I'm afraid that storage controller goes through iommu too and crash causes some random writes to disk :(. But may be I am wrong and this ACPI call is illegal in reality and amdgpu does something wrong regarding iommu to. Nevertheless amdgpu works with iommu=off fine. Maybe the problem is with some buggy BIOS/firmware from vendor. I will try a newer kernel.

[Kernel-packages] [Bug 1747463] Re: kernel crashes during boot unless IOMMU is disabled on Ryzen 1800X
@Peridot, Request from Upstream: For the original 4.13 kernel, I don't see any attachments that have the AMD-Vi messages in question. Were they completion timeouts (like in the later mainline kernel test, which I'll get to in a bit) or I/O page fault messages? Without that information it is hard to determine what the issue really is. (Just as an FYI, if the IOMMU is disabled in BIOS, then iommu=soft is not necessary on the kernel command line). For the upstream kernel test, since this is a Ryzen system, it's possible that the BIOS does not have a requisite fix for SME and IOMMU (see [1]). On the upstream kernel, if memory encryption is active by default without this BIOS fix, then the result is AMD-Vi completion-wait timeout messages. Try booting with mem_encrypt=off on the kernel command line or build a kernel with CONFIG_AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT=n and see if that allows the kernel to boot. Thanks, Tom [1] https://bugzilla.kernel.org/show_bug.cgi?id=199513 ** Bug watch added: Linux Kernel Bug Tracker #199513 https://bugzilla.kernel.org/show_bug.cgi?id=199513 -- 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/1747463 Title: kernel crashes during boot unless IOMMU is disabled on Ryzen 1800X Status in Linux: Unknown Status in linux package in Ubuntu: Triaged Status in linux source package in Bionic: Triaged Status in linux source package in Cosmic: Triaged Bug description: I'm on a Ryzen 1800X and Biostar B350GT5 on bionic kubuntu.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.
