Description: I have a HP ProBook 455 G2 which has an AMD
A8-7100 Radeon R5, 8 Compute Cores 4C+4G. System started the
boot process and after some time I got following recurring
error messages:
AMD-Vi: Completion-Wait loop timed out and AMD-Vi: Event logged [IOTLB_INV_TIMEOUT device=... It corrupted my root partition. If to boot with ioomu=soft kernel parameter or if disable a discrete graphics card from BIOS, then booting fine. Additional info: Kernel (4.8.*-4.10.8) and amdgpu driver installed from official repositories. Hardware info attached. |
This task depends upon
Dmesg shows: AMD-Vi: Completion-Wait loop timed out
Boot is only possible using "iommu=soft" as boot option, in Arch and Fedora 26.
The problem is present on linux, linux-lts and linux-mainline
