3.15.2 dmesg log
I've an AMD M4N78 PRO (Bios 1303) motherboard [1] here having
a MCP78S chipset (GeForce 8300 onboard, PCI-ID 10de:0848)
where I get all black consoles with KMS.
Please note that X11 works fine.
Fortunately no lockups when switching VTs either.
I think there is probably a problem with KMS hand-over.
Reproducible at least with:
* vanilla 64-bit kernel 3.15.2 and 3.14.8
* openSUSE 13.1/x86_64 (3.11.10 kernel)
* grml64-2014.03 live CD with 3.13.6 kernel [2]
Yes, I've read:
http://nouveau.freedesktop.org/wiki/KernelModeSetting/
The consoles disappear (black only) once Nouveau switches
to its framebuffer. If KMS is disabled, the consoles stay
visible, i.e. vesa-fb works.
Console switching still works, i.e. switching to/from VT7
where X11 runs fine is possible. When switching, the
display goes black but switching back to VT7 restores
the X11 display.
When using fbcon=map:1 kernel parameter, behavior changes
just slightly when console switching: The X11 screen stays
(no switch to black screen) but seems to freeze. Switching
back to VT7 enables X11 again.
Btw, the Linux Penguins shown for each CPU core are displayed
but are distorted and in false colors. They disappear after
about 10 seconds when the VT screens goes all black.
Below are more details:

NOTE: Yes, this isn't the lastest but X11 is working.
This bug is about the console framebuffer.
I'm adding the Xorg log because it might provide some clues.
