Sorry for my English , you may anything if you don't understand what I wrote: I just tried jump over and boot with kernel 4.16-rc3, which also don't boot One new : kernel 4.16-rc3 and 4.15.6 boots well if I add nouveau.modeset=0 kernel-4.15-git3 and kernel-4.15-git6 doesn't boot or hang even with nouveau.modeset=0 but maybe it is unrelated
