Ivan Danov, 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> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc5 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. ** Summary changed: - System freeze on high memory usage + [NP900X4C-A04US] System freeze on high memory usage ** Tags removed: needs-computer-model -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1162073 Title: [NP900X4C-A04US] System freeze on high memory usage Status in “linux” package in Ubuntu: Incomplete Bug description: When I use MATLAB and all 8GB of RAM are full, system freezes and only a hard restart can get it working. I have found that the same bug is around since 2007 in the bug report at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/159356, but it was not fixed. Since Christopher M. Penalver insisted for re-reporting the bug and none have done it yet, I decided to report it. I have tested it with the newest kernel http://kernel.ubuntu.com/~kernel- ppa/mainline/v3.9-rc4-raring/ and it still persists.
