Public bug reported: Kernels since 4.2-rc1 contain:
[8fb55197e64d5988ec57b54e973daeea72c3f2ff] drm/i915: Agressive downclocking on Baytrail which causes hangs on my Bay Trail based Asus X553MA and likely on other Bay Trail based machines as well. The hangs occur between minutes and hours after booting and there is no information found related to them in kernel message buffer. I found the above commit by doing bisection between 4.1.0 and 4.2-rc1 and reported it to intel-gfx mailing list: http://lists.freedesktop.org/archives/intel-gfx/2016-January/084203.html I tested that these hangs occur with 14.04 LTS using latest linux-generic-lts-wily (4.2.0-23-generic) kernel exactly as with any kernel beginning from 4.2-rc1 up to 4.4-rc8. I'm now writing this bug report running 4.4-rc8 with patches from the above commit removed because 4.2.0-23-generic just hanged while I was trying to send report. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1531865 Title: 4.2 (linux-generic-ltw-wily) kernel hangs on Bay Trail based Asus X553MA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1531865/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
