Would be nice to see the output of
gdb /lib/modules/..../nvidia.ko
disassemble nvc0_vm_map_sg
Looks like there's a null deref in there (CR2 = 0). Although I think that
optimus mode isn't supposed to be well-supported right now. But we still
shouldn't be oopsing the kernel.

--- Comment #6 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
Well, +0x8e is +142, and we see
0x0000000000023bae <+142>: mov (%rcx,%r13,1),%rax
0x0000000000023bb2 <+146>: shr $0x8,%rax
0x0000000000023bb6 <+150>: mov %rax,%rdx
0x0000000000023bb9 <+153>: or $0x3,%rax
0x0000000000023bbd <+157>: or $0x1,%rdx
which I'm fairly sure corresponds to
u64 phys = nvc0_vm_addr(vma, *list++, memtype, target);
Since
static inline u64
nvc0_vm_addr(struct nouveau_vma *vma, u64 phys, u32 memtype, u32 target)
{
phys >>= 8;
phys |= 0x00000001; /* present */
if (vma->access & NV_MEM_ACCESS_SYS)
phys |= 0x00000002;
(And for some reason it splits the two branches into two separate registers...
odd, but nothing else in the code matches up as nicely.)
So that means that the passed in list pointer must be null. This corresponds to
drivers/gpu/drm/nouveau/nouveau_bo.c:nouveau_vma_getmap which passes in
mem->mm_node as the mem argument to vm_map_sg, which in turn does mem->pages.
So perhaps add something to the top of nouveau_vma_getmap (before the vm_get
call) like
if (WARN_ON(!node->pages)) {

}
Which should help avoid the crash, but will not provide any additional
functionality. You should then see a backtrace, but no crash.

Actually, that should probably be WARN_ON(mem->mem_type != TTM_PL_VRAM &&
!node->pages) otherwise you'll get a lot of spurious warns/failures.

I tested the most recent Fedora 18 kernel update (3.9.9-201.fc18.x86_64), and
the bug is still there. I enabled Optimus in the BIOS, booted to Linux, tried
to enable nouveau DVI output, and the kernel crashed immediately.
Then I built a custom kernel based on 3.9.9-201.fc18.x86_64 with the attached
patch included (as suggested above), and booted with that. Now there's a
problem.. nouveau outputs are not detected, and cannot be enabled, so I don't
know if the patch fixes or works around the problem. At least it breaks
something :)
There are no obvious nouveau related errors in the dmesg.. attached aswell.

That last dmesg looks fine... what's the problem? (It seems unlikely that
merely adding a WARN_ON that never fires would fix things, points to a compiler
issue? Or a different config/compilation mechanism/??)
You now have an intel and nvidia devices. I think it starts out with the intel
device, you can use the regular vga_switcheroo mechanisms to switch to the
nvidia device. Some docs about it are available at
https://help.ubuntu.com/community/HybridGraphics. If you're aware of all that,
can you be more specific as to what you're doing and what exactly doesn't work?

Ok, sorry for not explaining properly.
With the stock fedora 3.9.9-201 kernel the nouveau dvi outputs are detected OK,
so in the Mate desktop display properties application I can see the external
monitor that is connected with DVI, and I can choose to enable it, which causes
the kernel crash.
Now with the custom 3.9.9-201.dbg01 kernel that I built, which only has the
warn_on patch added on top of the stock kernel, the nouveau outputs are *not*
detected at all, so I can't see the DVI monitor on the display properties
application, and I can't enable the DVI monitor..
I tried rebooting the laptop multiple times, and the behaviour stays the same.
Maybe I should play with xrandr aswell. And probably rebuild a new kernel, with
that patch removed and see if it really causes the issue..
Thanks for your reply!

I assume you have a 1920x1080 screen hooked up to the DVI?
You can look at the KMS status in /sys/class/drm/ -- you should see
cardN-DVI-I-N directories. xrandr should also provide accurate status, e.g.:
$ grep . /sys/class/drm/card*-*/status
/sys/class/drm/card0-DVI-I-1/status:connected
/sys/class/drm/card0-DVI-I-2/status:disconnected
However it may end up being hidden due to vgaswitcheroo -- so make sure to look
into that too. (Unfortunately I know next to nothing about vgaswitcheroo, but
I'm sure Google knows more.)

--- Comment #14 from Pasi Kärkkäinen <pasik-X3B1VOXEql0@public.gmane.org> ---
Ok, after a lot of reboots and trying different kernels I realized the issue is
not related to the warn_on patch I added. The difference is caused by the fact
that if I boot with DVI monitor connected before powering on the system, or
not.
So what happens is:
1) I boot to Linux with DVI monitor connected to nouveau before powering on the
system. This is how it looks then:
$ grep . /sys/class/drm/card*-*/status
/sys/class/drm/card0-LVDS-1/status:connected
/sys/class/drm/card0-VGA-1/status:disconnected
/sys/class/drm/card1-DP-1/status:disconnected
/sys/class/drm/card1-DP-2/status:connected
/sys/class/drm/card1-DP-3/status:disconnected
/sys/class/drm/card1-LVDS-2/status:disconnected
/sys/class/drm/card1-VGA-2/status:disconnected
DP-2 is the external DVI monitor. So it's listed as "connected", but xrandr
doesn't see it:
$ xrandr
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192
LVDS1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 309mm x
174mm
1600x900 60.0*+ 40.0
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
Nothing about the nouveau adapter in xrandr output..
2) I boot to Linux with DVI monitor NOT connected to nouveau. I connect the DVI
cable after the system has booted to Xorg. This is how it looks then:
$ grep . /sys/class/drm/card*-*/status
/sys/class/drm/card0-LVDS-1/status:connected
/sys/class/drm/card0-VGA-1/status:disconnected
/sys/class/drm/card1-DP-1/status:disconnected
/sys/class/drm/card1-DP-2/status:connected
/sys/class/drm/card1-DP-3/status:disconnected
/sys/class/drm/card1-LVDS-2/status:disconnected
/sys/class/drm/card1-VGA-2/status:disconnected
So again DP-2 is shown as connected to the DVI monitor, which is true.
$ xrandr
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192
LVDS1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 309mm x
174mm

800x600 60.3 56.2
640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
LVDS-2 disconnected (normal left inverted right x axis y axis)
VGA-2 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 connected (normal left inverted right x axis y axis)

1024x768 60.0
800x600 60.3 56.2
640x480 60.0
DP-3 disconnected (normal left inverted right x axis y axis)
1024x768 (0x8e) 65.0MHz
h: width 1024 start 1048 end 1184 total 1344 skew 0 clock 48.4KHz
v: height 768 start 771 end 777 total 806 clock 60.0Hz
800x600 (0x8f) 40.0MHz
h: width 800 start 840 end 968 total 1056 skew 0 clock 37.9KHz
v: height 600 start 601 end 605 total 628 clock 60.3Hz
800x600 (0x90) 36.0MHz

v: height 600 start 601 end 603 total 625 clock 56.2Hz
And now xrandr can see the DVI monitor aswell. So when I plug-in the DVI cable
on-the-fly to nouveau adapter, then the external display is actually detected,
and can be enabled and used (with artifacts/corruption, but that is a separate
bug ;)
So 'xrandr' shows the same problem as I described earlier with the Mate desktop
display-properties GUI application. When the laptop is booted with DVI cable
plugged in from the start, the mate-display-properties GUI doesn't allow me to
enable the DVI monitor - so the behaviour matches xrandr. I assume
mate-display-properties internally uses xrandr.
But this sounds like an another bug really..

xrandr not working if booted with DVI cable connected doesn't seem to be the
case *always*.. it's seems to be a bit random. one boot out of 10, or so, I'm
able to see the nouveau connectors on xrandr, so I'm able to try to enable
them, and thus hit the warn_on in the patch I added to the kernel. So here
goes:

Oh, one more interesting piece of information..
If I boot (power-on) the laptop *without* DVI cable connected, the nouveau
connectors will show up in 'xrandr' output as DP-1, DP-2 and DP-3.
Now If i boot (power-on) the laptop *with* DVI cable connected, the nouveau
connectors will *NOT* show up in 'xrandr' most of the times, but during that
maybe one time out of ten when they do show up in 'xrandr', they're actually
called DisplayPort-0, DisplayPort-1 and DisplayPort-2.
I wonder why that difference.. and if it's related to the issue I'm having or
not. I'm only able to hit the nouveau kernel crash when the connectors are
called DisplayPort-X, it seems. When the connectors are called DP-X, I'm not
able to crash the kernel.

I think I'll open a separate bug about the non-consistent/random output
detection for xrandr and changing connector names.
So let's focus on the kernel crash and troubleshooting that in this bug.
Any comments about the WARNING traceback I posted?

Ok separate bug opened:
"nouveau inconsistent changing output connector names in xrandr":
https://bugs.freedesktop.org/show_bug.cgi?id=68075
So let's focus on the kernel crash on this bug.
I just verified the same kernel crash also happens on Linux 3.10.4.

I built custom Linux 3.10.6 kernel with the patch from this bug's attachments
(linux-3.9.9-gpu-drm-nouveau-warn-on-node-pages.patch) applied to add WARN_ON()
to nouveau_vma_getmap() and I'm still hitting the same issue when enabling an
output on nouveau gpu, which would lead to a hard kernel crash without the
patch:

Any comments about this issue?
The patch (linux-3.9.9-gpu-drm-nouveau-warn-on-node-pages.patch) from comment
#9 fixes the reproducible hard kernel crash for me.. should we push this to
Linux, or should we dig deeper about why nouveau_vma_getmap() is called with
wrong arguments resulting in null pointer crash?

We should figure out why it's getting stuff that it doesn't expect. I had
suggested adding the warn solely to avoid the crash down the line. I guess it's
reasonable for the upstream kernel to have that, as if it ever fires, we're
going to be in trouble later... I think. Will have to re-check the code. I can
post it with my analysis if you like, or you can.
Could you retest this with 3.11-rc6 BTW? The whole fb pinning/etc logic was
reworked, and your issue may have been fixed by it.

Feel free to post it with your analysis! You can add my reported-by and
tested-by.
I'm able to reproduce the crash with Linux 3.8.x, 3.9.x and 3.10.x, so the
patch is needed at least on the 3.10.x stable branch to fix the crash there.
I'll also test with 3.11-rc.

Some comments here.. this bug is still being discussed on the mailing lists,
and Ben Skeggs said he'll take a look at the kernel side fixes soon.
Also good to know: I'm able to reliably reproduce this kernel crash with Fedora
18 userspace/xorg, but not with Fedora 19 userspace/xorg.

FWIW, my patch, which was deemed inappropriate for inclusion:
http://marc.info/?l=dri-devel&m=137713025702333&w=2
Later in the thread, another patch was proposed:
http://marc.info/?l=dri-devel&m=137715564208095&w=2
However I don't think it has made it upstream yet as Ben had some concerns.

the latest patch mentioned on lkml thread only changes hard system locks
into soft locks for kernel-3.12.6-300.fc20.x86_64. the suspend/resume cycles
works pretty stable for rawhide kernel-3.13.0-0.rc7.git0.2.fc21.x86_64.
afaics, the 3.13 kernel contains some acpi/pm fixes in the nouveau area.
