hi, linux folks, I'm seeing an 'unable to handle kernel paging request' after loading busybox elf loading. The context table is now pointing a new pgd table and the releavant pgd table entry is pointing null. What could be the cause? the address to access is frame buffer that I had linux allocate from consistent memory region. (I'm borrowing arm dma_alloc_writecombine conde in arch/arm/mm/dma-mappping.c for sparc.) Something is wrong duing the process address space allocation. (I'm reading a book section while doing this..) Any hint will be greatly appreciated. Thanks!
