--- Comment #15 from Salah Coronya <salah.coronya at gmail.com> ---
Yes, it still does (as of 3b56bba6abaa70d629fccdcf8490e087ea3a1ab4 in
mouveau-master) it unles the workaround in Comment 12 (set the resolution an
mnaully disable the phantom ports on the kernel command line)  is applied.

There (at least) 2 symptoms - first, the syslog is spammed with
"[drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC:10]
message." Second, the framebuffer conole is set with a phyical resolution of
1280x1024 but a virtual resolution of 720x576 - so as a result is only fills
part of the screen, and it can't be changed with fbset (ioctl
FBIOPUT_VSCREENINFO: Invalid argument) - and attempting to do so generated more
syslog spam

X11 displays normally, however, (it picks a resolution 1024x768  and fills the
screen) - though it still spams the syslog.
