Juan Carlos Amengual, the next step is to fully reverse commit bisect from kernel 4.4 to 4.7-rc4 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. After the fix commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your help. ** Tags removed: confirmed ** Tags added: bios-outdated-2.07 kernel-fixed-upstream-4.7-rc4 needs-reverse-bisect -- You received this bug notification because you are a member of Kernel Packages, which is subscribed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/1595969 Title: Suspend doesn't work in ACER laptop Status in linux package in Ubuntu: Incomplete Bug description: I bought this laptop three years ago. Used Kubuntu 14.04 and 15.04 without **any** problem. A couple of weeks ago I installed Kubuntu 16.04 as always (formatting /root partition and doing a fresh install, not an upgrade). Since then both suspend and hibernation hang the laptop: the screen goes black, the laptop seems to stop but it won't. After a couple of minutes the fan can be heard and there is no way to restart linux. I have to power off the laptop (the hard way) and then turn it on. I have followed some threads and it seems that this is a common bug (it happens in several different hardware configurations). The original 4.4.0-22-generic kernel has been updated to versions 23 and 24 (current) but no way. The bug is still present. Thanks a lot in advance!
