Hello, I think I’ve seen this before when the GPU was not able to get enough
watts from the power supply. The log indicates the GPU was able to move on. Was
this the case. There are brown outs based on insufficient power from a power
company. If you see a lot of these please invest in a Unterruptable power
supply from a relyable company such as ApC or cyberpower. What is the specs of
the power supply if you don’t mind me asking. If this error persists we can
walk you through how to enable IOMMU should this be an option in the bios.

Definition from Wikipedia
“In computing, an input–output memory management unit (IOMMU) is a memory
management unit (MMU) that connects a direct-memory-access–capable
(DMA-capable) I/O bus to the main memory. Like a traditional MMU, which
translates CPU-visible virtual addresses to physical addresses, the IOMMU maps
device-visible virtual addresses (also called device addresses or I/O addresses
in this context) to physical addresses”

Is this a physical or virtual machine context.

Cheers, Rob Wahl
