There is no official Debian kernel 4.5 yet, as far as I know.

Peter Sasisanas has discovered a problem with the interaction between the nouveau driver and the powerpc64 (aka ppc64) kernel.  I don't understand the details, but it seems to have something to do with large pages not being compatible with the nouveau driver.

So Peter has generated a series of ppc64 kernels that don't use large pages.  They are available here:

open one of the folders (the 4.5.0-rc2 kernel works OK with Debian Stretch on my PowerMac G5) and download the two .deb files you find in the folder.

Install both of them using "dpkg -i ….deb". Modify /etc/yaboot.conf to use the new kernel.  Run "ybin -v".  And reboot.  Maybe you'll see a working graphical sign in screen.

Peter may know if there's any chance of his changes (or something like them) getting into mainstream Debian in the future.  It may be difficult, because whether or not you want large pages depends on you particular hardware, so it would not be possible to have one standard config for all ppc64 machines.

It's worth a try, anyway!
