--- Comment #6 from Jan Vesely jv356@scarletmail.rutgers.edu --- I managed to get IOMMU working by passing "amd_iommu=pt ivrs_ioapic[32]=00:14.0" on the kernel commandline. Now it's back to square one. all clover kernels hang the GPU unless I limit VM size to 'vm_size = min(vm_size, 1ULL << 40);' otherwise the machine works (including 3d graphics and suspend/resume).
