--- Comment #19 from Emil Velikov <emil.l.velikov at gmail.com> ---
Almost the same issue as originally, short on memory :'(

I admit some work on optimising such cases for low (gpu/vram) memory may be
needed, but I do not think it high up the priority list. Read - it's a most
likely a gem/ttm work than nouveau specific. Either way anyone is welcome to
give it a crack

Following the messages from xorg.log

drmmode_crtc_shadow_allocate >
nouveau_allocate_surface >
(libdrm) nouveau_bo_new >
(most likely) drmCommandWriteRead(dev->fd, DRM_NOUVEAU_GEM_NEW...) >
(kernel) nouveau_gem_ioctl_new >
(most likely) nouveau_gem_new >
chaos x)
