Spoke too soon. Rebooted and had the same hard lockup again. This time I had my camera within reach, so here's the trace: device_to_iommu+0x33/0x73 domain_context_mapping_one+0x37/0x335 domain_context_mapping+0x25/0xa7 iommu_prepare_identity+0xd7/0xf3 intel_iommu_init+0x4e4/0x8f3 ? mutex_lock ? sysctl_net_init ? pci_iommu_init pci_iommu_init I also have stack, code and register values. Let me know if you need them. Or I can just post the picture :-) Again, very latest git tree, VT-d enabled. /D -- Dirk Hohndel Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
