Marcin Jabrzyk, thank you for reporting this and helping make Ubuntu better.
Could you please capture the crash via https://help.ubuntu.com/community/DebuggingSystemCrash ? Also, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to 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 exactly shown as: kernel-fixed-upstream-3.19-rc2 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. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER 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. ** Tags added: kernel-bug-exists-upstream-3.17 needs-upstream-testing ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1407986 Title: Kernel hard freeze at random time (very often) Status in linux package in Ubuntu: Incomplete Bug description: The hardware is Dell Vostro V131 notebook. While using the system at random moments kernel hardfeezes. Ther are no inforamtions logged nowhere. The view on the screen is just freezing, nothing works except hard power off. I was trying REISUB etc. I was thingking this is SSD/RAM failure but after replacing them the bug still exists. Tried mainline kernel 3.17 from PPA the bug still exists. I haven't found what causes excalcy this bug ie. software/hardware. Sometimes it is working many hours and nothing happends and sometimes just after few seconds after boot the system is hardfreezed.
