Yup, nothing new there. We already have to deal with that with filesystems made on a 64k page architecture with a 64k block sizw. They can't be mounted and used on an architecture with a 4k page size, because the linux kernel does not support block size > page size.

FAT filesystems can have a "cluster size" bigger than page size, Linux probably only reject "device minimum access block size" > page size

What does one do in that situation?

This is not an idle question; I have inherited an apparently-Linux-based hard disk video recorder (now deceased) which seems to have created an ext3 file system with 8k blocks.

mount it on something that has larger than 4K block size. IIRC this can be done with powerpc, sparc, and I think even AMD64 systems
