In ARM64 Hyper-V UFS filesystem is getting corruption and those corruptions are consistently happening just after hitting a page boundary. It is unable to correctly read disk blocks into buffers that are not aligned to 512-byte boundaries. It happens because storvsc needs physically contiguous memory which may not be the case when bus_dma needs to create a bounce buffer. This can happen when the destination is not cache-line aligned. Hyper-V VMs have VMbus synthetic devices and PCI pass-thru devices that are added dynamically via the VMbus protocol and are not represented in the ACPI DSDT. Only the top level VMbus node exists in the DSDT. As such, on ARM64 these devices don't pick up coherence information and default to not hardware coherent.
