            Bug ID: 95193
           Summary: Nouveau not working with Quadro K2200 (NV117) and
                    Debian Wheezy
           Product: xorg
           Version: unspecified
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: joachim-NDHQTyUf4y2zQB+pC5nmwQ@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

LinuxCNC Live CD (Debian Wheezy is the base distribution) hangs with some
Nouveau messages.

Since I'm not allowed to install it on a PC with K2200 in our facility, I can
just use the LiveCD or USB-Stick with persistence mode. Is it somehow possible
to get a kernel log in this situation?

You can try the livecd at https://nouveau.pmoreau.org/ which should have a more
up-to-date stack.

Looks like some sort of issue training the DP link. Can you try a more recent
kernel? A bunch of DP things have been fixed since kernel 4.1.

@Ilia,

Done. Slapped on Fedora Core 23 (the installer runs 4.2.x kernel, which seems
to have the same issue as its 4.1.x cousins), but upon an update run, kernel
4.4.8-300 was installed, and things work. 

Attached the dmesg output from the 4.4.8-300, for reference. 

The overall goal is to run Qubes OS, so not sure if a later kernel is possible.
Not sure if there's a way to backport 4.4.8's nouveau/drm into a 4.1.3
(probably not, but hey, I can haz hopes?)

Cheers.

In kernel 4.1.x's output, there are "link training failed" messages, but in
4.4.x's, there are EDID checksum error messages instead. Wonder if 4.4.x's
version simply handles ASUS' EDID brainfart better than 4.1.x?

Not sure what backport means... like grabbing the 4.4.8 kernel and editing
Makefile to say that the version is 4.1.3? Anyways, this sort of thing isn't
something we tend to worry about -- enough troubles as it is.

Link training and EDID fetch are moderately separate items. I think a number of
changes went into the DP logic to harden it against various things that
monitors do.

Since this is fixed in recent kernels, I'm going to close this.
