There is some other weird stuff going on, but this is unlikely to be related to cache maintenance: - multiple occurrences of OF: translation of DMA address(0) to CPU address failed node(...) - /cpus/cpu@0: unsupported enable-method property: psci Then, there is not enough vmalloc space to map the config space of both PCIe RCs. Also, due to the fact that this platform sadly honours the ARM recommendation on memory maps, it seems there is no way to make useful use of any memory beyond 2 GB, given that the hole between the lower 2 GB and the upper <30 GB eats up all the lowmem by being covered by the memmap[] array. (Note that this platform supports up to 64 GB, in which case another hole of 480 GB is created, so there is no way we can even boot with that much memory reported to the kernel) Shell> initrd initrd.gz Shell> zImage EFI stub: Booting Linux Kernel...
