[Bug 1083836] Combination of 4.4.116+ kernel with older KMP makes user-space crashing
http://bugzilla.suse.com/show_bug.cgi?id=1083836 http://bugzilla.suse.com/show_bug.cgi?id=1083836#c2 --- Comment #2 from Jiri Slaby <jslaby@suse.com> --- Created attachment 762604 --> http://bugzilla.suse.com/attachment.cgi?id=762604&action=edit strace of X with drm-kmp installed OK, I do not understand the issue at all (yet). I see no way how a rebuild can help when the patch applied (neither after looking at the sync_core changes jikos mentioned). I can (perhaps) reproduce in qemu with 3d enabled (gl=on). It is enough to start X and glxgears. With 4.4.119, drm-kmp installed, it does not spin at all and X crashes after killing glxgears (screen's root window is NULL). Strace of X is attached (read from /dev/dri/card0 repeatedly returns -EFAULT). When I uninstall drm-kmp-default and reboot, the wheels are spinning and the reads return 32 bytes or so. I will attach strace of this in the next round. -- You are receiving this mail because: You are on the CC list for the bug.
