Public bug reported: Binary package hint: xorg
My HTPC has run various ubuntu's, but with 10.10 (fully up to date, but happened since the install) its X segfaults randomly. I can reproduce a crash eventually by simply running amarok and/or amule (so its not just KDE or GTK related), but haven't tried any other X applications. It takes anywhere between seconds and hours to crash once either or both of those applications has started. And it happens both when controlling the applications (normally via x11vnc) or when I'm not even connected to the screen (so no vnc client). It does however not occur with the normal mythtv fullscreen desktop (perhaps too little changes?) and not during hours of video-playback using mplayer. During the latest test, I had gdb running along side of X and was going to post the stack trace. But apparently, it hit some kind of run-away recursion, and I gave up trying to find the last few lines of the stack trace once I passed stack frame #130000 (I have no idea if gdb can show a reversed backtrace?). I have taken a core-dump with gdb at that time, which I've attached with this report. The backtrace ended with these lines repeated basically forever: #0 RecordAReply (pcbl=0x8204f00, nulldata=0x0, calldata=0xbede40a8) at ../../record/record.c:601 pContext = 0x0 pRCAP = <value optimized out> eci = 0 majorop = <value optimized out> client = 0x0 __PRETTY_FUNCTION__ = "RecordAReply" #1 0x08073866 in _CallCallbacks (pcbl=0x8204f00, call_data=0xbede40a8) at ../../dix/dixutils.c:743 cbr = 0x899c7d8 pcbr = <value optimized out> #2 CallCallbacks (pcbl=0x8204f00, call_data=0xbede40a8) at ../../dix/dixutils.c:877 No locals. #3 0x080a4b6f in WriteToClient (who=0x8b82300, count=116, __buf=0x8c01ac8) at ../../os/io.c:800 replylen = 21 bytesleft = <value optimized out> n = <value optimized out> replyinfo = {client = 0x8b82300, replyData = 0x8c01ac8, dataLenBytes = 116, bytesRemaining = 0, startOfReply = 1} oc = 0x8bfaae0 oco = <value optimized out> padBytes = 0 #4 0x0093728e in RecordFlushReplyBuffer (pContext=0x8c01ab0, data1=<value optimized out>, len1=0, data2=0x0, len2=0) at ../../record/record.c:251 No locals. #5 0x00937314 in RecordFlushAllContexts (pcbl=0x8204f04, nulldata=0x0, calldata=0x0) at ../../record/record.c:867 eci = 2 pContext = 0xbede40a8 #6 0x08073866 in _CallCallbacks (pcbl=0x8204f04, call_data=0x0) at ../../dix/dixutils.c:743 cbr = 0x899c820 pcbr = <value optimized out> #7 CallCallbacks (pcbl=0x8204f04, call_data=0x0) at ../../dix/dixutils.c:877 No locals. #8 0x080a4a54 in WriteToClient (who=0x8b82300, count=116, __buf=0x8c01ac8) at ../../os/io.c:824 oc = 0x8bfaae0 oco = <value optimized out> padBytes = 0 #9 0x0093728e in RecordFlushReplyBuffer (pContext=0x8c01ab0, data1=<value optimized out>, len1=0, data2=0x0, len2=0) at ../../record/record.c:251 No locals. #10 0x00937314 in RecordFlushAllContexts (pcbl=0x8204f04, nulldata=0x0, calldata=0x0) at ../../record/record.c:867 eci = 2 pContext = 0xbede40a8 #11 0x08073866 in _CallCallbacks (pcbl=0x8204f04, call_data=0x0) at ../../dix/dixutils.c:743 cbr = 0x899c820 pcbr = <value optimized out> #12 CallCallbacks (pcbl=0x8204f04, call_data=0x0) at ../../dix/dixutils.c:877 No locals. #13 0x080a4a54 in WriteToClient (who=0x8b82300, count=116, __buf=0x8c01ac8) at ../../os/io.c:824 oc = 0x8bfaae0 oco = <value optimized out> padBytes = 0 #14 0x0093728e in RecordFlushReplyBuffer (pContext=0x8c01ab0, data1=<value optimized out>, len1=0, data2=0x0, len2=0) at ../../record/record.c:251 No locals. #15 0x00937314 in RecordFlushAllContexts (pcbl=0x8204f04, nulldata=0x0, calldata=0x0) at ../../record/record.c:867 eci = 2 pContext = 0xbede40a8 #16 0x08073866 in _CallCallbacks (pcbl=0x8204f04, call_data=0x0) at ../../dix/dixutils.c:743 cbr = 0x899c820 pcbr = <value optimized out> #17 CallCallbacks (pcbl=0x8204f04, call_data=0x0) at ../../dix/dixutils.c:877 No locals. #18 0x080a4a54 in WriteToClient (who=0x8b82300, count=116, __buf=0x8c01ac8) at ../../os/io.c:824 oc = 0x8bfaae0 oco = <value optimized out> padBytes = 0 #19 0x0093728e in RecordFlushReplyBuffer (pContext=0x8c01ab0, data1=<value optimized out>, len1=0, data2=0x0, len2=0) at ../../record/record.c:251 No locals. #20 0x00937314 in RecordFlushAllContexts (pcbl=0x8204f04, nulldata=0x0, calldata=0x0) at ../../record/record.c:867 ProblemType: Bug DistroRelease: Ubuntu 10.10 Package: xorg 1:7.5+6ubuntu3 ProcVersionSignature: Ubuntu 2.6.35-23.41-generic 2.6.35.7 Uname: Linux 2.6.35-23-generic i686 NonfreeKernelModules: nvidia .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX x86 Kernel Module 260.19.06 Mon Sep 13 06:35:06 PDT 2010 GCC version: gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5) Architecture: i386 Date: Sat Dec 11 22:02:19 2010 DkmsStatus: nvidia-current, 260.19.06, 2.6.35-22-generic, i686: installed nvidia-current, 260.19.06, 2.6.35-23-generic, i686: installed MachineType: Gigabyte Technology Co., Ltd.
