hi onkar sure so I searched what dbus package was upgraded : dbus-X11 and after test dbus is not the source of the bug
so i did this 1.format all and complete re-installation in ext3 or ext2 same bug , same solution ( upgrade except grub packages) therefore when i shutdowned , many reboot with running manually fsck 2.format all and complete re-installation in ext4 same bug , same solution ( upgrade except grub packages) But when I shutdown no fsck needed at reboot so i think the bug is probabely done by grub -- Boot fails with Out of Range Pointer error https://bugs.launchpad.net/bugs/424503 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
