Kevin, the next step is to fully reverse commit bisect from kernel 4.4 to 4.7-rc5 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. ** Description changed: + Xorg crashes about every 45 minutes. + Jun 7 11:40:18 kevin-MacBookPro kernel: [ 6818.471186] Freezing of tasks failed after 20.007 seconds (1 tasks refusing to freeze, wq_busy=0): Jun 7 11:40:18 kevin-MacBookPro kernel: [ 6818.471220] Xorg D ffff880089ccfa78 0 1109 1099 0x00400004 Jun 7 11:40:18 kevin-MacBookPro kernel: [ 6818.471230] ffff880089ccfa78 ffffffff812cbfa8 ffff880264d99b80 ffff88025d450000 Jun 7 11:40:18 kevin-MacBookPro kernel: [ 6818.471237] ffff880089cd0000 ffff880089ccfab0 ffff88026ec8dd00 ffff88026ec8dd00 Jun 7 11:40:18 kevin-MacBookPro kernel: [ 6818.471242] 0000000000000001 ffff880089ccfa90 ffffffff81821205 000000010018eca0 Jun 7 11:40:18 kevin-MacBookPro kernel: [ 6818.471248] Call Trace: Jun 7 11:40:18 kevin-MacBookPro kernel: [ 6818.471263] [<ffffffff812cbfa8>] ?
