Hi, This is a kernel bug and i've opened a report there. https://bugzilla.kernel.org/show_bug.cgi?id=33582 but i heard that opening a bug here was appropriate. if not, i :(, please close. I'm able to successfully hibernate while using nouveau with kernel version 2.6.35 (and before) but unable to hibernate in 2.6.36 (and after up to 2.6.39-rc2). I am not using X. From the console I test whether hibernate is possible using "pm-hibernate". I've bisected this and located a range of possible commits which changed this behavior. last known good: d17f395cdcec39033a481f96d75e8b3d3c41d43a first known bad: 816544b21b020bdb9dcb9a5003fe3e1f109e8698 Between these commits the kernel would not compile.

Thanks, Chad.
I probably can't help you with hibernation bug, but if you would post a compile error I could provide a patch or workaround, so you could continue bisecting this. Please attach dmesg from last known good and first bad kernel. Dmesg from .39-rcX might be useful too.

Created attachment 45983 [details] dmesg of "last good" kernel boot
Created attachment 45984 [details] dmesg of "first bad" kernel boot
Created attachment 45985 [details] dmesg of 2.6.39-rc4 kernel boot
Here are what appear to be the relevant parts of dmesg for the "last good" and "first bad" kernels. The difference I see is that the "last good" emits "failed parsing" messages, whereas the "last bad" does not. I will attach the full dmesg separately.

If anyone can devise a patch to fix up the compile error that would be nice! Here is the first compile error encountered after the "last good" commit: CC [M] drivers/gpu/drm/nouveau/nouveau_drv.o CC [M] drivers/gpu/drm/nouveau/nouveau_state.o CC [M] drivers/gpu/drm/nouveau/nouveau_channel.o CC [M] drivers/gpu/drm/nouveau/nouveau_mem.o CC [M] drivers/gpu/drm/nouveau/nouveau_object.o drivers/gpu/drm/nouveau/nouveau_object.c: In function 'nouveau_gpuobj_new': drivers/gpu/drm/nouveau/nouveau_object.c:236:23: error: 'struct drm_mm' has no member named 'ml_entry' make[4]: *** [drivers/gpu/drm/nouveau/nouveau_object.o] Error 1 make[3]: *** [drivers/gpu/drm/nouveau] Error 2 make[2]: *** [drivers/gpu/drm] Error 2 make[1]: *** [drivers/gpu] Error 2 make: *** [drivers] Error 2
Created attachment 45995 [details] [review] compile fix Ok. Here's the temporary compile fix. (ml_entry was renamed to node_list in commit d1024ce91ff4c2c4ccbf692d204c71cbf215157a ("drm: sane naming for drm_mm.c"), but nouveau tree was rebased before pulling) Before continuing bisection can you revert commit 309b8c89c8ddf9dd8e5f253c185d6af1d0358a79 on top of e.g. 816544b21b020bdb9dcb9a5003fe3e1f109e8698 and see if it fixes hibernation?
Thanks for the compile fix work around! I've completed the git bisect: 190a43783f2c43186180c827444d4eac901b4bcf is the first bad commit commit 190a43783f2c43186180c827444d4eac901b4bcf Author: Francisco Jerez <currojerez@riseup.net> Date: Thu Jun 17 12:42:14 2010 +0200 drm/nouveau: Don't clear AGPCMD completely on INIT_RESET. We just need to clear the SBA and ENABLE bits to reset the AGP controller: If the AGP bridge was configured to use "fast writes", clearing the FW bit would break the subsequent MMIO writes and eventually end with a lockup. Note that all the BIOSes I've seen do the same as we did (it works for them because they don't use MMIO), OTOH the blob leaves FW untouched.

(In reply to comment #9) > Created an attachment (id=46048) [details] > possible fix > > commit description does not match patch body, so let's apply commit description > and see if it fixes your issue Unfortunately this did not fix the hibernate problem. I tested on both 2.6.39-rc4 and modifying the original commit on the development tree. Do you have another try? :) Thanks, C.
Created attachment 46068 [details] [review] revert+debug Please attach dmesg from successful resume with this patch applied. It's a revert + some debugging. Attaching VBIOS from your card might be helpful too. http://nouveau.freedesktop.org/wiki/DumpingVideoBios
> Please attach dmesg from successful resume with this patch applied. It's a > revert + some debugging. Actually, I've only been able to successfully _resume_ from hibernate using Debian's 2.6.32 with backported nouveau drivers. 2.6.33 only successfully hibernates, i.e. writes to disk and shuts off. When turning on the % loaded reaches 100%, then there is a dark screen. I guess to track down the successful resume one would have to look at Debian's patches to 2.6.32. Would you still be interested in dmesg and vbios for a successful write to disk only? :)
It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report. In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one. Thanks, The Nouveau Team
