James Ferguson, the next step is to fully reverse commit bisect from kernel 4.4 to 4.7-rc3 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 ** Tags added: bios-outdated-2.66 ** Tags added: kernel-fixed-upstream-4.7-rc3 needs-reverse-bisect regression-release ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1591790 Title: Resume from suspend, lock screen causes gpu hang Status in linux package in Ubuntu: Incomplete Bug description: Frequently, returning from suspend, the lock screen 'crashes'. I typically enter my password, it freezes (sometimes shows me my desktop) and then I get the lock screen again, presumably it's respawned.
