Plamen, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com /~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.
If the latest kernel 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 issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: bios-outdated-2202 ** Tags added: latest-bios-2202 ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Low => Medium ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1510821 Title: Ubuntu Freezes With No Obvious Reason Status in linux package in Ubuntu: Incomplete Bug description: I am dev and I know how this sounds but at a certain periods ubuntu freezes entirely. The only exit is the power button. I dont know what could be helpful information in this case so I will write everything I noticed so far (sry for the spam). This used to happen a lot while building with Android Studio but lately it freezes even when the studio is closed. The last time it happened after I closed(or tried to) Chrome tab while updating ubuntu. This behavior started a few weeks ago. I haven't updated to 15.10 at the time so I did. But it still continued to block. I thought it might be from the video driver so I switched from nvidia-340 to nouveau with no success. I cant find anything helpful in kern.log if its needed I can attach the log just before the freeze. What I find strange is in the syslog. At the time of the freeze it is filled with NULs. See attached image syslog.png. The time of the freeze was around 8:57. At this point the mouse cursor was active but there was nothing that reacted to my desperate clicks or keyboard shortcuts. After awhile the mouse stops as well and there is nothing I can do but the power button. Is there some other log that could be helpful or anything else I can do?
