Kernel 4.8.0-32 introduced changes from the mainline kernels 4.8.7, 4.8.8, 4.8.9, 4.8.10 and 4.8.11 . In my testing, 4.8.8 works fine and suspend is broken starting with 4.8.9. Furthermore, suspend is still broken with the latest 4.8 kernel which is 4.8.17 (therefore the tag kernel-fixed-upstream might not be appropriate).
Do you have any kind of infrastructure to find regressions in kernels? For example, something that would automatically build kernels for every commit between 4.8.8 and 4.8.9 so that I can try to find the culprit by bisection? ** Bug watch added: Linux Kernel Bug Tracker #192471 http://bugzilla.kernel.org/show_bug.cgi?id=192471 ** Also affects: linux via http://bugzilla.kernel.org/show_bug.cgi?id=192471 Importance: Unknown Status: Unknown -- 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/1655065 Title: Regression: Suspend broken on Thinkpad P50 with 4.8.0-32-generic Status in Linux: Unknown Status in linux package in Ubuntu: Confirmed Status in linux source package in Yakkety: Confirmed Bug description: Suspending to ram and to disk works perfectly fine on the 4.8.0-30-generic kernel. On 4.8.0-32-generic it works some of the time, but most of the time it freezes the machine. When the machine is frozen the screen is turned off, the power button light is on, but the machine does not respond to any input including the Magic SysRq keys, the only thing that can be done is powering off the machine by pressing the power button for 10 seconds. This happens both with suspend-to-ram and suspend-to-disk.
