Ivrs workarounds no longer needed, but kernel will complain early on that it cannot find smbus and iommu, but will later in the boot process detect and load them (race condition?). So far working and temps are cool, fan doesn't come on nearly as much. Going to try newer kernels in increments. Can confirm this are working on the a315-41 without boot args so far.
