system randomly hardlocks T530

[Hasdai Westbrook]

System started randomly hardlocking about 3 weeks ago. Hardlock doesn't seem to be related to open programs, usually chrome and some other basic programs are open.
When hardlock happens, switching TTYs is not possible also none of the logs(syslog, kern, dmesg, Xorg) show any kind of error.

Ran memtest with no errors found.

All packages up to date with current LTS repos

Kernel 3.2.0-49-generic
Ubuntu 12.04.2 LTS

I helped Hasdai file this bug, it probably has something to with the Graphics Environment.
Can't be more specific on the package, we found no explicit errors pointing at Xorg, but when this happens everything freeze, the screen stays up and both mouse and keyboard freeze.

Assuming its Xorg or perhaps the intel graphics driver? This has "only" been happening off and on for the last 3 weeks or so

Hasdai Westbrook, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux REPLACE-WITH-BUG-NUMBER

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
