While it is true that the ACPI spec says that the flag is only valid on Extended Address Space Descriptors, examples of other descriptors in the spec use the ProducerConsumer flag explicitly, and real hardware uses it as well. In fact, even in the ASL of the Thunder X2 for which r330113 was a workaround, some devices use this flag on non-Extended Address Space Descriptors correctly. Instead, only ignore the flag for resources associated with the UART devices on the Thunder X2 using the "ARMH0011" HID to identify these devices. This should fix regressions from ignoring this flag in other contexts such as Hyper-V. PR: 235876 Reported by: Wei Hu <weh@microsoft.com> Tested by: emaste (Thunder X2) MFC after: 2 weeks

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
