2018-07-27 Thread Roger Pau Monne
Several people have reported hardware issues (malfunctioning USB controllers) due to iommu page faults. Those faults are caused by missing RMRR (VTd) or IRVS (AMD-Vi) entries in the ACPI tables. Those can be worked around on VTd hardware by manually adding RMRR entries on the command line, this is
