Or is there another > explanation that I'm overlooking? Hmm, could you try init=/bin/sh? If the shell invoked successfully it might be COW issue. In this case, could you try deleting __HAVE_ARCH_COPY_USER_HIGHPAGE in include/asm-mips/page.h? If init=/bin/sh not worked, COW is irrelevant and something would be wrong around flush_dcache_page/update_mmu_cache. But no idea now ... --- Atsushi Nemoto
