On an LPAE system, the physical addresses used by VirtIO-MMIO may be higher than 32 bits. For example on a Versatile Express system with 4G RAM, the following error surfaces when trying to use a VirtIO-MMIO block device. EXT2-fs (vda): error: ext2_check_page: bad entry in directory #2: : unaligned directory entry - offset=0, inode=3755990991, rec_len=57311, name_len=223 To fix this, select ARCH_DMA_ADDR_T_64BIT when LPAE is selected and mach-vexpress, mach-virt, or both are being built.
