--- Comment #5 from Stuart Longland <[email protected]> --- I'll put a "me too" up. I can toss up logs for X.org however I've got a challenge trying to get dmesg out of the machine: local console becomes unresponsive and I have to hard-reboot to recover. An exerpt from X.org logs: (EE) [mi] EQ overflowing. Additional events will be discarded until existing events are processed. (EE) (EE) Backtrace: (EE) 0: /usr/bin/X (xorg_backtrace+0x4f) [0x7f17a02c94bf] (EE) 1: /usr/bin/X (mieqEnqueue+0x2b3) [0x7f17a02a81d3] (EE) 2: /usr/bin/X (0x7f17a00e8000+0x73a6a) [0x7f17a015ba6a] (EE) 3: /usr/bin/X (xf86PostMotionEvent+0xd0) [0x7f17a019e580] (EE) 4: /usr/lib64/xorg/modules/input/synaptics_drv.so (0x7f17979fc000+0x5694) [0x7f1797a01694] (EE) 5: /usr/lib64/xorg/modules/input/synaptics_drv.so (0x7f17979fc000+0x71f2) [0x7f1797a031f2] (EE) 6: /usr/bin/X (0x7f17a00e8000+0xa3a57) [0x7f17a018ba57] (EE) 7: /usr/bin/X (0x7f17a00e8000+0xd34a0) [0x7f17a01bb4a0] (EE) 8: /lib64/libpthread.so.0 (0x7f179f27a000+0x11250) [0x7f179f28b250] (EE) 9: /lib64/libc.so.6 (ioctl+0x7) [0x7f179dfab297] (EE) 10: /usr/lib64/libdrm.so.2 (drmIoctl+0x38) [0x7f179f0704b8] (EE) 11: /usr/lib64/libdrm.so.2 (drmCommandWrite+0x2b) [0x7f179f07335b] (EE) 12: /usr/lib64/libdrm_nouveau.so.2 (nouveau_bo_wait+0x99) [0x7f179aa7a0e9] (EE) 13: /usr/lib64/xorg/modules/drivers/nouveau_drv.so (0x7f179ac7f000+0xd0ae) [0x7f179ac8c0ae] (EE) 14: /usr/lib64/xorg/modules/drivers/nouveau_drv.so (0x7f179ac7f000+0xd601) [0x7f179ac8c601] (EE) 15: /usr/bin/X (DRI2SwapBuffers+0x27d) [0x7f17a029642d] (EE) 16: /usr/bin/X (0x7f17a00e8000+0x1afa30) [0x7f17a0297a30] (EE) 17: /usr/bin/X (0x7f17a00e8000+0x5bbbe) [0x7f17a0143bbe] (EE) 18: /usr/bin/X (0x7f17a00e8000+0x6017a) [0x7f17a014817a] (EE) 19: /lib64/libc.so.6 (__libc_start_main+0xf5) [0x7f179deead55] (EE) 20: /usr/bin/X (0x7f17a00e8000+0x47fed) [0x7f17a012ffed] (EE) (EE) [mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack. (EE) [mi] mieq is *NOT* the cause. It is a victim. (EE) [mi] EQ overflow continuing. 100 events have been dropped. I don't have a second machine handy to use SSH with right now. My host is running Gentoo AMD64 with Linux kernel 3.18.5, X.org server 1.15.2, xf86-video-nouveau 1.0.10 and mesa 10.2.6. The machine is an Apple MacBook A1278 with a NVidia GeForce 9400M. The kernel was built this morning from git sources (linux-stable git tree). I'm finding OpenSCAD 2014.03 triggers the bug pretty reliably. I can be booted in X running Firefox, Thunderbird, QTerminal and FVWM for *days*, but after about 5 minutes of fiddling with models in OpenSCAD, *boom*, nouveau accidentally says something insulting to the GPU and the GPU stops communicating. -- You are receiving this mail because: You are the assignee for the bug.
