Upgrading to critical: This is a bug that meets all of the following: "A bug which has a severe impact on a large portion of Ubuntu users
Causes data corruption Crashes the entire operating system Renders the system temporarily or permanently unusable Severely affects applications beyond the package responsible for the root cause " ** Changed in: xserver-xorg-input-synaptics (Ubuntu) Importance: High => Critical ** Description changed: + Crash on resume in xserver-xorg-input-synaptics. Version + 1.5.99.902-0ubuntu5 works, the workaround is to downgrade to that + version. + + It appears to hit many newer laptops causing data loss. + + + Original description + Happens quite often, but I can't find a pattern to when it happens. Might be related to either firefox or Minecraft (openjdk-6) but I am not certain. #10 <signal handler called> No symbol table info available. #11 XIGetDeviceProperty (dev=0xb9238788, property=277, value=0xbffa7cdc) at ../../Xi/xiproperty.c:852 - handler = <optimized out> - prop = 0xb923c8d8 - rc = <optimized out> + handler = <optimized out> + prop = 0xb923c8d8 + rc = <optimized out> #12 0xb7667797 in get_property (dev=<optimized out>, property=277, type=19, offset=0, length=1, bytes_after=0xbffa7d84, type_return=0xbffa7d8c, format=0xbffa7d7c, nitems=0xbffa7d80, length_return=0xbffa7d78, data=0xbffa7d88, delete=<optimized out>, client=<optimized out>) at ../../Xi/xiproperty.c:290 - n = <optimized out> - len = <optimized out> - ind = <optimized out> - rc = <optimized out> - prop = <optimized out> - prop_value = <optimized out> - + n = <optimized out> + len = <optimized out> + ind = <optimized out> + rc = <optimized out> + prop = <optimized out> + prop_value = <optimized out> ProblemType: Crash DistroRelease: Ubuntu 12.04 Package: xserver-xorg-core 2:1.11.4-0ubuntu6 ProcVersionSignature: Ubuntu 3.2.0-18.29-generic-pae 3.2.9 Uname: Linux 3.2.0-18-generic-pae i686 .tmp.unity.support.test.0: ApportVersion: 1.94.1-0ubuntu2 Architecture: i386 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz Date: Thu Mar 15 08:30:43 2012 DistUpgraded: Fresh install DistroCodename: precise DistroVariant: ubuntu ExecutablePath: /usr/bin/Xorg ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GraphicsCard: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:21c5] InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Alpha i386 (20120304) MachineType: LENOVO 02173BG ProcCmdline: /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none ProcEnviron: ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.2.0-18-generic-pae root=UUID=f58bc641-2db1-4b1d-a839-3b04dc4e9ee2 ro quiet splash vt.handoff=7 SegvAnalysis: Segfault happened at: 0xb7667528 <XIChangeDeviceProperty+440>: mov 0x8(%esi),%eax PC (0xb7667528) ok source "0x8(%esi)" (0x00000009) not located in a known VMA region (needed readable region)! destination "%eax" ok SegvReason: reading NULL VMA Signal: 11 SourcePackage: xorg-server StacktraceTop: XIGetDeviceProperty () ??
