Curious observation: [ 78.633151] BUG: unable to handle kernel paging request at f84c8000 [ 78.633265] IP: [<f8fb6be9>] nouveau_bo_wr32+0x29/0x60 [nouveau] [ 78.633430] *pdpt = 0000000001b79001 *pde = 0000000034c88067 *pte = 0000000000000000 [ 50.751850] BUG: unable to handle kernel paging request at f84c8000 [ 50.751967] IP: [<f8f51be9>] nouveau_bo_wr32+0x29/0x60 [nouveau] [ 50.752139] *pdpt = 0000000001b79001 *pde = 0000000034c88067 *pte = 0000000000000000 [ 68.844824] BUG: unable to handle kernel paging request at f8598000 [ 68.845087] IP: [<f8f17be9>] nouveau_bo_wr32+0x29/0x60 [nouveau] [ 68.845475] *pdpt = 0000000001b79001 *pde = 0000000034c88067 *pte = 0000000000000000 [ 183.768120] BUG: unable to handle kernel paging request at f8498000 [ 183.768233] IP: [<f8e91be9>] nouveau_bo_wr32+0x29/0x60 [nouveau] [ 183.768402] *pdpt = 0000000001b79001 *pde = 0000000034c88067 *pte = 0000000000000000 [ 107.772418] BUG: unable to handle kernel paging request at f848d000 [ 107.772538] IP: [<f8e4cbe9>] nouveau_bo_wr32+0x29/0x60 [nouveau] [ 107.772718] *pdpt = 0000000001b79001 *pde = 0000000034c88067 *pte = 0000000000000000 The pdpt/pde/pte values are always the same. Perhaps that's just the unmapped page or something. Other observations: 32-bit kernel. One instance of a cal_space exhaustion, but it recovered apparently. Does this patch help at all? http://lists.freedesktop.org/archives/nouveau/2015-June/021416.html I believe the conditions are the same as the ones I hit... 25: 01 f2 add %esi,%edx ... 2b:* 89 0a mov %ecx,(%edx) <-- trapping instruction ESI: f84b8000 EDX: f84c8000 So you're going over the 0x10000 size of the ring. How should I test your implementation/fix? Apply the patch to your kernel, compile, install, boot. I'm sure you can find some instructions online for your distro if you're not already familiar with the process. Hi Ilia, I tried to create a kernel-version with the applied patch, but I had several problems: 1. this https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1460768 bug occurred 2. such a bug occurred: ----------------------- Note: Writing hsi_event.9 Warn: meta author : no refentry/info/author hsi_get_channel_id_by_name Note: meta author : see http://docbook.sf.net/el/author hsi_get_channel_id_by_name Warn: meta author : no author data, so inserted a fixme hsi_get_channel_id_by_name Note: Writing hsi_get_channel_id_by_name.9 gzip -f Documentation/DocBook/man/*.9 make[3]: Leaving directory '/media/h/C_SSD/kernel2/linux-source-3.19.0' debian/ruleset/targets/doc.mk:34: recipe for target 'debian/stamp/install/linux-doc-3.19.8-ckt2' failed make[2]: *** [debian/stamp/install/linux-doc-3.19.8-ckt2] Error 2 make[2]: Leaving directory '/media/h/C_SSD/kernel2/linux-source-3.19.0' debian/ruleset/common/targets.mk:357: recipe for target 'debian/stamp/do-install-indep' failed make[1]: *** [debian/stamp/do-install-indep] Error 2 make[1]: *** Auf noch nicht beendete Prozesse wird gewartet … make[3]: Leaving directory '/media/h/C_SSD/kernel2/linux-source-3.19.0' ====== making target debian/stamp/BIN/linux-image-3.19.8-ckt2-dbg [new prereqs: do-pre-bin-arch pre-linux-image-3.19.8-ckt2-dbg]====== ====== making target debian/stamp/dep-binary-arch [new prereqs: pre-bin-arch linux-headers-3.19.8-ckt2 linux-image-3.19.8-ckt2 linux-image-3.19.8-ckt2-dbg linux-uml-3.19.8-ckt2]====== make[2]: Leaving directory '/media/h/C_SSD/kernel2/linux-source-3.19.0' make[1]: Leaving directory '/media/h/C_SSD/kernel2/linux-source-3.19.0' dpkg-buildpackage: Fehler: Fehler-Exitstatus von fakeroot debian/rules binary war 2 debian/ruleset/targets/common.mk:401: recipe for target 'debian/stamp/build/buildpackage' failed make: *** [debian/stamp/build/buildpackage] Error 2 h@h:/media/h/C_SSD/kernel2/linux-source-3.19.0$ ----------------------- I think I tried to apply this patch up to 5 times, but it didn't worked. Could you please provide a working kernel-version with the applied patch? At least that would be very helpful. I have no ideas how I should proceed otherwise. It's like I'm trying something and it is always a dead end. By the way, the compile needed 11 hours and to see that it didn't work afterwards is very frustrating. I hope you can help me with that and I will be able to apply a kernel-version with the applied patch. Thanks in advance Best regards Jedet The patch in question should be included in kernels 4.2+ and potentially some of the older stable trees. The upstream patch is: commit d108142c0840ce389cd9898aa76943b3fb430b83 Author: Ilia Mirkin <imirkin@alum.mit.edu> Date: Mon Jun 29 04:07:20 2015 -0400 drm/nouveau/fbcon/nv11-: correctly account for ring space usage Jadet Ilrihm, 15.04 is EOL as of February 4, 2016. For more on this, please see https://wiki.ubuntu.com/Releases . If this is reproducible in a supported release, it will help immensely if you filed a new report with the Ubuntu repository kernel (not mainline/upstream) via a terminal: ubuntu-bug linux Please feel free to subscribe me to it.

Created attachment 115959 [details] System log file of 7 BUGs in nouveau Problem description: -------------------- GUI freezes. No user interaction (mouse, keyboard) possible. Only hard shutdown possible. System specifications: ---------------------- - Operating System: Ubuntu 15.04. - Computer-Hardware: Acer Aspire 7520p - Graphic-Card: Nvidia 7000m Steps to reproduce: ------------------- 1. Start Ubuntu and log in 2. wait or accelerate the freeze by 2.1. starting firefox 2.2. starting a terminal Why it looks like a nouveau bug? -------------------------------- Well, I see something like the following in /var/log/systemlog each time, when the GUI freezes.
