My version of the crash is an initial [drm] nouveau 0000:01:00.0: GPU lockup - switching to fbcom \n and similar repeated messages of "Failed to idle channel 1. (or 2), all interleaved with full screen patterns of color block patches.
It is interesting that while I see mp4 videos from edx.org classes, what really exacerbates the problem is alt-tab between screens. My first real indication of a problem is when alt-tab produces a solid triangle of color on the bottom right half of the display. the diagonal goes from the bottom left of the left monitor to the top right of the right monitor. Shortly after that the system becomes unusable, and power button for reboot. I have not gotten to the point of opening up port 22 to remotely connect to the system. This is a clean install of 12.10, and all of the updates are current. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1033533 Title: Xorg crashed with SIGABRT: exaMemcpyBox with src=0x0 on nouveau with SW rendering Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Status in “xserver-xorg-video-nouveau” source package in Quantal: Confirmed Status in “xserver-xorg-video-nouveau” source package in Raring: Confirmed Bug description: Crash doing memcpy in EXA on nouveau, with software rendering activated. #8 <signal handler called> No symbol table info available. #9 __memcpy_sse2 () at ../sysdeps/x86_64/multiarch/../memcpy.S:72 No locals. #10 0x00007f570e63684e in memcpy (__len=23, __src=0x0, __dest=0x7f5713877100) at /usr/include/x86_64-linux-gnu/bits/string3.h:52 No locals. #11 exaMemcpyBox (pbox=pbox@entry=0x7fffef000de0, src=0x0, src_pitch=64, dst=0x7f5713877100 "", dst_pitch=24, pPixmap=<error reading variable: Unhandled dwarf expression opcode 0xfa>) at ../../exa/exa_migration_classic.c:59 i = 16 cpp = <optimized out> bytes = 23 #12 0x00007f570e636d03 in exaCopyDirty (migrate=migrate@entry=0x7fffef000e40, pValidDst=0x7f5713dc3e40, pValidSrc=0x7f5713dc3e50, transfer=0x7f570f28b7f0 <nouveau_exa_download_from_screen>, fallback_index=fallback_index@entry=1, sync=0x7f570e635780 <exaWaitSync>) at ../../exa/exa_migration_classic.c:240 pPixmap = 0x7f5713dc3da0 pExaPixmap = 0x7f5713dc3e00 damage = <optimized out> CopyReg = {extents = {x1 = 0, y1 = 0, x2 = 23, y2 = 16}, data = 0x0} save_use_gpu_copy = 1 save_pitch = 64 pBox = 0x7fffef000de0 nbox = 1 access_prepared = 1 need_sync = 0 #13 0x00007f570e636f32 in exaCopyDirtyToSys (migrate=migrate@entry=0x7fffef000e40) at ../../exa/exa_migration_classic.c:285 pPixmap = <optimized out> pExaScr = 0x7f5713877100 pExaPixmap = 0x0 #14 0x00007f570e63951a in exaPrepareAccessReg_mixed (pPixmap=0x7f5713dc3da0, index=<optimized out>, pReg=0x0) at ../../exa/exa_migration_mixed.c:254 as_dst = 1 pixmaps = {{as_dst = 0, as_src = 1, pPix = 0x7f5713dc3da0, pReg = 0x0}} pExaPixmap = 0x7f5713dc3e00 has_gpu_copy = <optimized out> success = <optimized out> [Original Report] The crash report started immediately after login.
