Systems with 256 CPU threads - IOMMU configuration# For systems that have 256 logical CPU cores or more (e.g., 64-core AMD EPYC™ 7763 in a dual-socket configuration and SMT enabled), setting the input-output memory management unit (IOMMU) configuration to “disabled” can limit the numb...
That could be a bad USB cable or device that is shorting out the USB port and triggering a current overload condition. 1) Do you have multiple USB buses in your PC? Does the problem occur on the other USB buses? In my case, my AMD USB 3.0 eXtensible Host Controller was stable while...

IOMMU is an extension to AMD64 architecture to support address translation and access protection on DMA transfers. Together, virtualization software runs more securely and efficiently enabling a better experience when dealing with virtual systems. Security for User Level application and Virtual Machine ...
And I have been told "AMD-Vi: Completion-Wait loop timed out" reported by IOMMU because of no response from the IO device, in my case, it is Intel X710 2x10GbE SFP+ Adapter, running with Debian 11 and Inbox driver for Intel X710. The failing system had LACP b...
