[Bug 330052] Re: Xvfb crashes with SIGSEGV in FreeColormap()
valgrind output shows that the immediate problem is that xrealloc in glx/glxscreen.c:276 causes some colormaps to have a bad pVisual member.. That is : some colormaps STILL point to the old memory .. In other words.. not all colormaps gets fixed up in AddScreenVisuals. Here is a gdb session where we track the colormaps created/destroyed. a...@durum:~/xvfb$ gdb --args Xvfb -auth hosts :1 GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.

[Bug 371191] Re: Corrupted file system ext3 after Jaunty 64 upgrade
Bug #360952 mentioned HPET (in fact I was the only one to comment on it). In any case.. The problem persists even after messing with HPET. So this did not solve it. However, manually installing Linux kernel 2.6.29.3 from source DID solve the problem (or at least the symptoms).

[Bug 360952] Re: Unstable system, EXT3 FS errors and boot failure
I am under the assumption that this problem is related to the HPET issues others are experiencing. With HPET (enabled by default), the system becomes unstable over time.. Installed Jaunty again and tried two kernels: one with HPET enabled and one with HPET disabled. So far, the system, with HPET disabled has not suffered from these problems, while the other consistently makes the FS corrupt. ** Tags added: kernel -- Unstable system, EXT3 FS errors and boot failure https://bugs.launchpad.net/bugs/360952 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 360952] [NEW] Unstable system, EXT3 FS errors and boot failure
Public bug reported: System is Ubuntu Jaunty amd64. Hardware is Lenovo T61, type 6460-D6G. System becomes unstable within minutes or a few hours of operation (uptime) and we see crashes in many places.. Mostly in apt-get (SEGVs), due to that being used heavily the first few hours of operation. Eventually the kernel will warn about EXT3-FS errors.. At next reboot Grub will be unable to list boot entries and show 'Error 2'. It is assumed this is a software failure rather than hardward because it happens on two different laptops (same T61 model) and 2) both laptops has been running for months with Ubuntu Intrepid (amd64/i386). Ubuntu Jaunty was installed twice on first T61 laptop and once on second T61 laptop. For the first laptop Ubuntu Jaunty was installed via upgrade and for the second time and on second laptop Ubuntu Jaunty was installed via Netboot. ** Affects: ubuntu Importance: Undecided Status: New -- Unstable system, EXT3 FS errors and boot failure https://bugs.launchpad.net/bugs/360952 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
