Dear Maintainer,
The latest testing 3.16.5 kernel is built with 64K pages:
***************************
$ cat /lib/modules/3.16-3-powerpc64/build/.config | grep 4K
CONFIG_PPC_HAS_HASH_64K=y
# CONFIG_PPC_4K_PAGES is not set
CONFIG_PPC_64K_PAGES=y
# CONFIG_SQUASHFS_4K_DEVBLK_SIZE is not set
**************************
The problem is that nouveau driver in kernel is unable to run with non-4K pages
(it's assuming 4k pages somehow).
There's a fix in nouveau ml for that, but it is not included in kernel. This is
causing gpu to stuck and switch to fb and screen in X become a bunch of squares
with parts of image within them, like in puzzle.
BTW, I can't build kernel ending with error: ld.bfd.real error: -T emulation
mode is not supported (writing by mem, so I might be wrong in exact string).
built with dpkg-buildpackage -j5 -a ppc64.
