[Nouveau] [Bug 95031] New: [NVE4] Random GPU lockups
https://bugs.freedesktop.org/show_bug.cgi?id=95031 Bug ID: 95031 Summary: [NVE4] Random GPU lockups Product: xorg Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Driver/nouveau Assignee: nouveau at lists.freedesktop.org Reporter: lucasout at gmail.com QA Contact: xorg-team at lists.x.org Created attachment 123085 --> https://bugs.freedesktop.org/attachment.cgi?id=123085&action=edit nouveau bugs Having random lockups on a GTX 660 Ti (NVE4), since kernel 4.1 I guess, using DRI2. [ 0.267666] nouveau 0000:02:00.0: NVIDIA GK104 (0e4030a2) [ 0.378583] nouveau 0000:02:00.0: bios: version 80.04.4b.00.1a [ 0.379302] nouveau 0000:02:00.0: fb: 2048 MiB GDDR5 Now on gentoo ~amd64 using: sys-kernel/gentoo-sources-4.5.1 x11-base/xorg-server-1.18.3 x11-drivers/xf86-video-nouveau-1.0.12 Also tried Karol Herbst reclocking branch v4 (https://github.com/karolherbst/nouveau/tree/stable_reclocking_kepler_v4), reclocked to pstate 07 and tried all 3 boost states. All hang sooner or later. Will continue testing other pstates and boost configurations. Sometimes the kernel log becomes corrupted, but I managed to get a working log (attached). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

[Nouveau] [Bug 95031] [NVE4] Random GPU lockups
https://bugs.freedesktop.org/show_bug.cgi?id=95031 --- Comment #1 from Lucas Ribeiro <lucasout at gmail.com> --- Forgot to add: did not try earlier kernels, so this behaviour might exist since the card was supported. On Windows it works well. It hangs on normal browsing or opening a video on VLC. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

[Nouveau] [Bug 95031] [NVE4] 660 Ti Random GPU lockups
https://bugs.freedesktop.org/show_bug.cgi?id=95031 --- Comment #4 from Lucas Ribeiro <lucasout at gmail.com> --- OK, some interesting findings. 07 pstate on Linux has: core 324 MHz memory 648 MHz AC DC GPU core: +0.99 V Increasing GPU core voltage to 1.09V has wielded a stable system so far. On Windows, the idle state has (checked with gpu-z): core 324 MHz memory 162MHz GPU core voltage: 0.99V It has never managed to hang. So maybe 07 pstate on Linux has a memory clock too high for its voltage. Also, as it is the lowest pstate, maybe memory clock could be reduced further to 162MHz (as in Windows). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

There are other issues which aren't exactly voltage related. If such a high votlage won't help, then it is usually something else, we just have to figure out what it is. Also regarding the lower clocks: yeah I know that sometimes nvidia clocks further down, but there is no real value in doing so if there is no voltage information for those low clocks and it doesn't make any difference regarding power consumption as far as I know. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
