https://bugzilla.kernel.org/show_bug.cgi?id=198243 Bug ID: 198243 Summary: nouveau: X11 server hangs while DPMS active Product: Drivers Version: 2.5 Kernel Version: 4.12.12 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: kernelbugs@xxxxxxxxxxxxxx Regression: No Created attachment 261315 --> https://bugzilla.kernel.org/attachment.cgi?id=261315&action=edit Xorg.0.log Symptom: DPMS is engaged, monitors off. Pressing keys has no effect. System is alive. ssh'ing in, trying xdpyinfo (or any X command) on :0.0 results in a hung client. Problem appeared between 4.9.34 and 4.12.12, sorry I can't narrow it down further. It happens within a few hours of boot, and has never hung while I'm actually doing something - only when I leave the keyboard and come back to DPMS-blanked system. Xorg server 1.19.5; hang has never happened on 4.9.34. It has happened twice in the last 24 hours on 4.14.8. strace on the X process yields rapid infinite loop of: ioctl(12, DRM_IOCTL_NOUVEAU_GEM_CPU_PREP, 0x7ffee9b26240) = ?
