Since i915 is built-in I suspect this simply moved something else in the kernel image around which provokes the bug. -Daniel > > bisection log: https://syzkaller.appspot.com/x/bisect.txt?x=13aeb522e00000 > start commit: c61a56ab Merge branch 'x86-urgent-for-linus' of git://git... > git tree: upstream > final crash: https://syzkaller.appspot.com/x/report.txt?x=106eb522e00000 > console output: https://syzkaller.appspot.com/x/log.txt?x=17aeb522e00000 > kernel config: https://syzkaller.appspot.com/x/.config?x=4013180e7c7a9ff9 > dashboard link: https://syzkaller.appspot.com/bug?extid=1e46a0864c1a6e9bd3d8 > syz repro: https://syzkaller.appspot.com/x/repro.syz?x=16bca207800000 > C reproducer: https://syzkaller.appspot.com/x/repro.c?x=14819a47800000 > > Reported-by: syzbot+1e46a0864c1a6e9bd3d8@xxxxxxxxxxxxxxxxxxxxxxxxx > Fixes: 4b6ce6810a5d ("drm/i915/cnl: > WaPipeControlBefore3DStateSamplePattern") > > For information about bisection process see: https://goo.gl/tpsmEJ#bisection > _______________________________________________ > dri-devel mailing list > dri-devel@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/dri-devel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
