The use of the driver in current kernels causes the system to freeze. It exits graphical state, exits to a tty. Some messages displayed on the screen. Can't copy & paste them. They are not to be found in /var/log/dmesg or /var/log/messages. The output on screen clearly implicates the nouveau driver. First line states along the lines of the kernel can not handle a page request. A few lines down it cites the nouveau driver. Wouls include a log if possible, not traceable. Supposedly error is output to stderr, not to a log. Reproducible: Sometimes Steps to Reproduce: 1. Boot in with driver. 2. Execute emerges. 3. Wait. Actual Results: The graphical state suddenly exits, taken to a tty as stated. Expected Results: stable state. It occurs in current tuxonice kernel, gentoo sources kernel, hardened kernel. The paging request falure suggests ksm involvement which has a history.

Given the date, it might just be too old for kernel - nouveau is still in heavy development. Try either in-kernel or a more recent ebuild.
x11-base/nouveau-drm is not intended for general use. Please enable in-kernel DRM instead. See http://www.gentoo.org/doc/en/xorg-config.xml#doc_chap2_sect3 for proper kernel configuration.
sorry to confuse. Not the drm package, the regular nouveau driver. That gentoo link is what I used to incorporate nouveau driver. Appears to be a regression. Was working fine, update world and update nouveau xorg driver breaks graphical. Other hints point at ksm as the underlying common denominator. in-kernel DRM was all enabled.
So the problem appears only if ksm is enabled?
(In reply to comment #5) > So the problem appears only if ksm is enabled? Chi; all my kernel config were much the same. kms was enabled on all. What i don't understand is the inplication that kms not be set. From my understanding it's required by nouveau. Anyway, a hint. Given this tip, I set gallium in make.conf and remerged and retried. so far with a small amount of usage, hasn't broken X but am currently switching kernels frequently.
Note that kms and ksm are two very different things.
(In reply to comment #7) > Note that kms and ksm are two very different things. Chi, Oh yes, so it is. Symbol: DRM_KMS_HELPER [=m] │ │ Symbol: DRM_I915_KMS [=n] │ │ Type : boolean │ Symbol: DRM_RADEON_KMS [=n] │ │ Type : boolean │ is all I get on searching with / in menuconfig. So, it did shatter X again. once again observing the snippet, it reads with last sysfs cmd /sys/devices/pci0000:00/0000:00:02.0/..../card0/ this is the video card. remaining lines are tech jargon, some hex addresses.
For a lack of better ideas, attach your kernel config. While Linus frown upon it, nouveau is still in a stage where kernel/xorg drivers incompatibilities happen. On that note, 2.6.38 was released a few hours ago.

The tuxonice is yet untouched since making the bug so that should be the best choice, it happens to be a 2.6.36, but that shouldn't spoil anything. As stated, followed the referenced guide in the first place to use the nouveau.
Created attachment 266045 [details] a kerenl config as requested config of the 2.6.36-tuxonice kernel
Created attachment 266087 [details] config 2.6.37-hardened-r5 It may help; was mostly using this hardened kernel, matches the system profile. On reflection it is also pretty well untouched. Am using it now and so far it's held; pattern of unpredictability about when and how it crashes. When it crashes, there's no escape.
devs: kernel 3.6.37 hardened crashed again. It took aver 2 hours b4 it decided to blow. General protection fault ..... SMP last sysfs file /sys/devices/pci0000:00/0000:00:0b.0/0000:02:00.0/drm/card0/card0-VGA-1/status ................ ................ and curiously the mouse was still working. . That I got from this tuxonice kernel system running nouveau, finally figured to use find in /sys. It's proving slippery, sometimes breaks after 5 minutes, sometimes some hours.
Can probably discard this one. Tracked down many incidents of system freezing to overheating. After some fan maintenance, a number of kernels are now stable with nouveau
