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. Attached are kernel messages using netconsle.

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.

There is some warning during call, but something happened :) ACPI Warning: \_SB.PCI0.VGA.PX02: Insufficient arguments - Caller passed 0, method requires 1 (20160930/nsarguments-256) I did this twice - one time with and one time without iommu=off.

You have very new amd gpu so Use the command: git clone -b drm-next-4.11-wip git://people.freedesktop.org/~agd5f/linux The kernel configuration file of Debian Official kernel are available in /boot, named after the kernel release. Copy the .config file to the linux directory. Connect all your devices and run the command: make localmodconfig. You can use the command make defconfig too for creating initial .config file. Use the command: make xconfig and check that you have enabled: Reroute Broken IRQ, Virtualization KVM and 300Hz CPU timer, I also disabled Swap, Kernel Debug, CPU Freq scaling , Cpu handling in Acpi, Used Bios to control CPU and devices. In the drivers->graphics->amdgpu enable cik support for a gcn 1.1 gpu and si support for a gcn 1.0 gpu. Create debian kernel package: export CONCURRENCY_LEVEL=4 fakeroot make-kpkg --initrd kernel_image Install the kernel package with Gdebi. To make a custom kernel to boot, add a line to /etc/initramfs-tools/modules: unix And run: sudo update-initramfs Reboot.

In the kernel configuration you can try to disable iommu and vgaswitcheroo. >From the kernel command line you can blacklist pci devices.

Laptop configs are A6-9220 radeon r4 5 compute cores 2c+3g, 4G RAM, 200GB Intel SSD (1st laptop) or 500GB Toshiba HDD (2nd laptop) I'm using OS ALT linux distribution (www.altlinux.org) Boot and installation of the system is performed flawlessly using LiveCD if LAN cable is NOT attached. dmesg shows plenty of "AMD-Vi: Completion-Wait loop timed out" errors. Connecting LAN cable during LiveCD boot results graphical target boot failure or kernel panic. After first reboot the system won't boot anyway and ext4 filesystem corruption occurs. As investigtion revealed that switching IOMMU off (amd_iommu=off and/or iommu=soft) solves the issue. "amd_iommu=fullflush" doesn't work for me. I've discovered several patches concerning solution of (amd_)iommu issues in linux-kernel mailing list archive, but they are either applied to kernels mentioned above already or their application doesn't solve the issue for me. Above mentioned patch (https://patchwork.freedesktop.org/patch/157327/) is not applicable to mentioned kernel versions any more. Therefore my question is: am I missing some patch that already solved the issue or should I provide more specific bug report?

There are lots of AMD-Vi logged events and I get irq crashes or acpi hangups with a 'normal' boot. I got it to boot by disabling IOMMU in the BIOS and adding "iommu=soft" to the kernel booting options in grub. linux can then detect everything properly (all cores) and I've had zero crashes. The only issue is that it's using software IOMMU which could have a performance penalty because it has to copy all the data of some PCI devices to sub 4G regions. Alternatively it boots with the kernel option "acpi=off" but only detects a single core/thread. I attached a kernel log.
