I've added iommu=pt to my kernel command line, and now have; [ 1.240242] AMD-Vi: Found IOMMU at 0000:00:00.2 cap 0x40
I was looking at IOMMU in the hope that my Win10 vmware guest would be more stable. No change, however. > APU? > I was under the impression that those CPU's used a different chipset, > not the 990FX. > Thanks for clearing up my confusion on the location of the IOMMU being the CPU, not the chipset. FWIW i'm using an FX-8350. The APU comment was with respect to CONFIG_AMD_IOMMU_V2. I believe FX CPU just uses CONFIG_AMD_IOMMU - that's certainly working for me with the FX-8350.
