After updating from 14.04 LTS to 16.04 LTS I see the same issue with Intel J1900 (also baytrail) and the current standard amd64 kernel 4.4.0-34. Video freezes and no input reaches the system any more. No possibility to get out of the deadlock, no keyboard and no further logs produced.
Some research pointed me to other users with the same problem, the initial description matches the case and is quite likely what Thomas Moestl also sees: http://askubuntu.com/questions/761706/ubuntu-15-10-and-16-04-keep- freezing-randomly I manually installed Kernel 4.7.0-040700rc3-generic #201606121131 SMP Sun Jun 12 15:34:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux and can confirm that the issue is solved with this. Unfortunately the current regular kernel does not work, but according to https://bugzilla.kernel.org/show_bug.cgi?id=109051 there is no definitive fix for this yet ** Bug watch added: Linux Kernel Bug Tracker #109051 http://bugzilla.kernel.org/show_bug.cgi?id=109051 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1530557 Title: Random hard freezes under X on a laptop with Intel BayTrail processor (ASUS R752MA) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1530557/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
