It panics with the message: Kernel panic - not syncing: Unable to find SBA IOMMU: Try a generic or DIG kernel Reverting this from next-20130605 fixes my problem and I can boot again. So please don't pull. -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
