I experienced this problem for the first time after upgrading my kernel to 3.7.9. With that kernel, my monitor no longer functioned, but only has a bouncing blue box that says, "PLEASE CHECK PC DISPLAY SETTINGS" Here is a copy of the last 'git bisect visualize' commit ebb945a94bba2ce8dff7b0942ff2b3f2a52a0a69 Author: Ben Skeggs <bskeggs@redhat.com> Date: Fri Jul 20 08:17:34 2012 +1000 drm/nouveau: port all engines to new engine module format This is a HUGE commit, but it's not nearly as bad as it looks - any problems can be isolated to a particular chipset and engine combination. It was simply too difficult to port each one at a time, the compat layers are *already* ridiculous. Most of the changes here are simply to the glue, the process for each of the engine modules was to start with a standard skeleton and copy+paste the old code into the appropriate places, fixing up variable names etc as needed. v2: Marcin Slusarz <marcin.slusarz@gmail.com> - fix find/replace bug in license header v3: Ben Skeggs <bskeggs@redhat.com> - bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and left no space for kernel's requirements during GEM pushbuf submission. - fix duplicate assignments noticed by clang v4: Marcin Slusarz <marcin.slusarz@gmail.com> - add sparse annotations to nv04_fifo_pause/nv04_fifo_start - use ioread32_native/iowrite32_native for fifo control registers v5: Ben Skeggs <bskeggs@redhat.com> - rebase on v3.6-rc4, modified to keep copy engine fix intact - nv10/fence: unmap fence bo before destroying - fixed fermi regression when using nvidia gr fuc - fixed typo in supported dma_mask checking Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Here's my bisect.log Bisecting: a merge base must be tested [28a33cbc24e4256c143dce96c7d93bf423229f92] Linux 3.5 Bisecting: 12468 revisions left to test after this (roughly 14 steps) [06d2fe153b9b35e57221e35831a26918f462db68] Merge tag 'driver-core-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Bisecting: 6387 revisions left to test after this (roughly 13 steps) [7f60ba388f5b9dd8b0da463b394412dace3ab814] Merge tag 'for-v3.7' of git://git.infradead.org/users/cbou/linux-pstore Bisecting: 3161 revisions left to test after this (roughly 12 steps) [a20acf99f75e49271381d65db097c9763060a1e8] Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next Bisecting: 1579 revisions left to test after this (roughly 11 steps) [ca41cc96b2813221b05af57d0355157924de5a07] Merge branch 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping Bisecting: 767 revisions left to test after this (roughly 10 steps) [d66e6737d454553e1e62109d8298ede5351178a4] Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6 Bisecting: 450 revisions left to test after this (roughly 9 steps) [df86b5765a48d5f557489577652bd6df145b0e1b] drm/savage: re-add busmaster enable, regression fix Bisecting: 218 revisions left to test after this (roughly 8 steps) [56d92aa5cf7c96c70f81d0350c94faf46a9fb76d] Merge tag 'stable/for-linus-3.7-x86-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen Bisecting: 120 revisions left to test after this (roughly 7 steps) [268d28371cd326be4dfcd7eba5917bf4b9d30c8f] Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next Bisecting: 48 revisions left to test after this (roughly 6 steps) [c4837d27945b9b607b5a7274a33059e73d1a7831] drm/nouveau/core: remove some left-over pieces from the porting process Bisecting: 24 revisions left to test after this (roughly 5 steps) [18c9b959fd8ea6f3602efbedad788f53e305e6f1] drm/nouveau/gpuobj: create wrapper functions for mapping gpuobj into vm/bar Bisecting: 12 revisions left to test after this (roughly 4 steps) [c4afbe74cebf887d3d8e7a11aa93bebcb6a3e2e1] drm/nvc0-/gr: share headers between fermi and kepler graphics code Bisecting: 6 revisions left to test after this (roughly 3 steps) [fce875d647171f9f740587a252fc026aaa421afe] drm/nouveau: move compat ioctl out of nouveau_drv.h Bisecting: 2 revisions left to test after this (roughly 2 steps) [08c770969a45361277d556f9fd3e2d70da42be65] drm/nouveau: start culling unused code Bisecting: 0 revisions left to test after this (roughly 1 step) [ebb945a94bba2ce8dff7b0942ff2b3f2a52a0a69] drm/nouveau: port all engines to new engine module format Bisecting: 0 revisions left to test after this (roughly 0 steps) [ac1499d9573f4aadd1d2beac11fe23af8ce90c24] drm/nvc0-/gr: generate grctx template at init time, not first context ctor ebb945a94bba2ce8dff7b0942ff2b3f2a52a0a69 is the first bad commit commit ebb945a94bba2ce8dff7b0942ff2b3f2a52a0a69 Author: Ben Skeggs <bskeggs@redhat.com> Date: Fri Jul 20 08:17:34 2012 +1000 drm/nouveau: port all engines to new engine module format This is a HUGE commit, but it's not nearly as bad as it looks - any problems can be isolated to a particular chipset and engine combination.

Created attachment 78003 [details] Xorg.0.log, while running 3.9.0-rc6
I've tried the direct approach here of staring at the commit. It all seems generally plausible, but as you probably noticed, it's quite rather large. I think that the way to go for solving this will be to run an mmiotrace of it working and then not working, and compare. Once we know exactly which functions aren't being called, it should be easier to figure out why. Would you be up for putting the two mmiotraces together? Here's a guide on how to do it: https://wiki.ubuntu.com/X/MMIOTracing (but replace "nvidia" with "nouveau"). You'll obviously need to compile nouveau as a module. BTW, I assume that the monitor goes blank as soon as the modesetting happens, not when X starts? It does seem to find your monitor, X gets EDID (which another NV1A user isn't getting, odd). But it just never turns the crtc on... or something. Also, could you provide some details about the physical hookup -- is this DVI-D (digital) or VGA/DVI-A (analog)? Is there just a single connector or are there multiple ones? What type(s) of connector? Lastly, might be worthwhile to just try the latest and greatest kernel (3.11-rc6). I have pretty low hopes for a fix to nv1a going in since 3.9, but who knows, something could have jiggered it.
Please try out https://bugs.freedesktop.org/attachment.cgi?id=84758 This helped another NV1A user.
This should be fixed in nouveau/master. If the problem remains, feel free to reopen.

Well, my fix only went into v3.13-rc1, so your 3.11 kernel almost certainly doesn't have the fix. Please try the latest rc kernel and see if your issue still appears there. Do note that not all is well with NV1A after this fix -- there is still another NV1A bug open about resume issues.
Thank you very much for your answer. I'm a bit in troubles with upgrading to 3.13, at the moment. But I manually applied your patch to current debian 3.11 source and it works perfectly for me Claudio
