Ubuntu 13.04 seems to randomly crash

[Juan Ascencio]

I'm using an x64 distro of Ubuntu 13.04 on a Dell inspiron 1464, but it keeps crashing for no apparent reason.

I tried accessing the logs and the computer crashed again.
I have Windows 7 on a dual boot and there doesn't seem to be any issue with it.

Executed memtest86+ as suggested and added the results to the rest of the captures.

It seems argle-bargle to me, but after inspecting the kernel log (/var/log/kern.log ) as somebody suggested and I noticed lines very similar to these just before the system crashed every time :

[ 1124.560208] type=1400 audit(1372790729.559:2): apparmor="STATUS" operation="profile_load" name="/sbin/dhclient" pid=2123 comm="apparmor_parser"
[ 1124.560634] type=1400 audit(1372790729.559:3): apparmor="STATUS" operation="profile_load" name="/usr/lib/lightdm/lightdm/lightdm-guest-session-wrapper" pid=2120 comm="apparmor_parser"
[ 1124.560690] type=1400 audit(1372790729.559:4): apparmor="STATUS" operation="profile_load" name="/usr/lib/x86_64-linux-gnu/lightdm-remote-session-freerdp/freerdp-session-wrapper" pid=2121 comm="apparmor_parser"

Anyway, I switched back to version 16-ish of the kernel (the version the installation came with) instead of the latest one (25-ish?) and the system won't crash anymore. I made a copy of the kernel log if anybody is interested.

I'm including this hoping it can be of use to anybody interested in this issue.
