There are a couple of things in kern.log.1 with 4.8.0-26, but if the dates in the log can be trusted they're from about a week ago.

One thing that you can try is checking dmesg and /var/log/kern.log from your successful boots to see if any oopses are logged in either place. If we can't get the kernel messages then we may have to resort to a bisect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1641976 Title: Kernel panics and boot problems in Zesty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1641976/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1641976] Re: Kernel panics and boot problems in Zesty
Okay, this is highly strange, and quite unpredictable. Because the boot console output in Fusion scrolled off and can't be captured (AFAICT), I don't have specifics, but there was definitely an oops and a kernel crash. At the end of the output I saw something like "recursive error fixed, reboot required". I didn't notice this before so I'd just restored an older known good snapshot and then went through the entire dist-upgrade path again, and each time got the same oops. But then I noticed this last line, instead of restoring the snapshot I just power cycled the VM (though the Fusion menu item). This time it booted successfully, and I did *not* notice an oops. Now the behavior is completely unpredictable. There seems to be a couple of end states when I boot this dist-upgraded Zesty VM, in roughly the order of most common to least common observation. 1) The console output scrolls by very quickly and the last thing I see is that lightdm is starting. Then the screen blacks and never comes back. Cannot log in. 2) Kernel oops ending with "invalid opcode: [#1] SMP" and a stack trace that I cannot see the bottom of. 3) Kernel oops which I can't see the top of, but includes a stack trace and ends in the message "BUG: unable to handle kernel paging request at 000ef62f811" 4) The boot process completes at the login screen, and I can log into the desktop just fine. 5) Console boot output proceeds seemingly as normal. The last thing I see is "[ OK ] Started Network manager Script Dispatcher Service" (although the last OK I see does change), then Fusion pops up a dialog that says "The CPU has been disabled by the guest operating system", meaning to me that the virtual CPU simply halted. Crazy! I'll see if there's some magic to get Fusion to capture the console output. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1641976 Title: Kernel panics and boot problems in Zesty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1641976/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

You're seeing the same usercopy crash? That doesn't make sense - zesty currently uses yakkety kernels, and the offending option is still disabled.
