dmesg-4.3.0-rc1-broken
Running kernel 4.3-rcX I can usually boot to a good nouveau session, however if I reboot the system the display is squashed and ghosted across the screen.
I have a capture of the kernel log showing a FIFO that has failed to reset. Rebooting again doesn't clear the error - nor does shutting down and starting again - I typically need to go and boot an older kernel ubuntu 3.13.0-58-generic in this case. I haven't tested shutting down the system for a prolonged period after the corruption yet.
Attached is the kernel log of
dmesg-4.3.0-rc1.txt (totally broken both screens)
dmesg-4.3.0-rc3.txt (totally broken both screens)
dmesg-4.3.0-rc3-onescreen-good.txt (totally broken on one screen)
Also note this error is readily replicated with one screen present - the laptop display. I'll attach a dump of that too.
