          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED

Application: systemsettings (4.11.8)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

1. Enabled network time server.

2. Set UTC as the system time

- Unusual behavior I noticed:

1. Kubuntu 14.04, 64 bit, Operating System repeatedly failed after two or three
startups and sometimes never started up and had to be reinstalled.

2. Even after reinstalling the OS it continued to fail.

3. The last time the OS failed was just before this problem occurred.

4. The OS reported the following information among several others when it
failed:

4.1. Kernel BUG at /build/buildd/linux-3.13.0/mm/filemap.c: 1371

4.2. invlid opcode: 0000[#2]SMP

etc., etc.

4.1. Kernel panic - not syncing: Attempted to kill init! exit code: 0x0000000b

4.2. drm_kms_helper: panicoccurred, switching bact to text mode

5. Thereafter, the OS remained stuck and was restarted by powering down and
powering up again. The current failure occurred shortly thereafter.

6. The following is some information on the hardware platform:

6.1. Processors: 4 x Intel Core i5 CPU M 450 @ 2.40 GHz.

6.2. Memory: 3.7 GiB of RAM

6.3. Computer System: Toshiba Notebook, Satelite, L676-01R

7. The following is some information on the software:

7.1. KDELibs Version: 4.13.0

7.2. Qt Version: 4.8.6

7.3. Kernel Version: 3.13.0-24-generic

7.4. OS Tye: 64-bit
