After updating kernel to HWE 4.15 I am not able to reboot or shutdown. When I try to reboot a black screen appears and everything freezes.

output of lspci -k | grep -EA3 'VGA|3D|Display':

00:02.0 VGA compatible controller: Intel Corporation Device 5916 (rev 02)
Subsystem: Lenovo Device 3988
Kernel driver in use: i915
Kernel modules: i915

    We will need more info than that. Did you upgrade to 16.04? What version did you upgrade from? Can you power-off by holding the power button? If so what happens on power-up? Can you power-off, power-on, and boot into Advanced option for Ubuntu? If you can get there we can try to diagnose from command-line. – SudoSURoot Jul 05 '18 at 15:25

    @SudoSURoot See https://askubuntu.com/questions/1052311/network-unclaimed-on-ubuntu OP upgraded the kernel to get Wi-Fi working. – Pilot6 Jul 05 '18 at 15:27

    Please [edit] your question and add output of lspci -k | grep -EA3 'VGA|3D|Display' terminal command. – Pilot6 Jul 05 '18 at 15:28
  • Is this OP even able to get to a terminal? That's the info I was trying to get. It reads like he is on a black screen and can't even shutdown. Wait for a reply, for more info, I guess. – SudoSURoot Jul 05 '18 at 15:45
  • @SudoSURoot I am able to power on and work properly on ubuntu , only problem is shuting down and reboot I guess. – Harsh Rawat Jul 05 '18 at 18:39

    Thanks for responding, I edited the question a bit, to be more clear on that. @Pilot6 is on 16.04 and knows about the kernel issues, if you update kernel to 4.15, which is not yet stable for 16.04 as far as I know. Just to be clear on that too, because it was edited, you are on 4.15 kernel, correct? What is output of uname -a – SudoSURoot Jul 05 '18 at 22:51
  • @SudoSURoot Bet you a dollar it is 4.15.0-24... – WinEunuuchs2Unix Jul 05 '18 at 23:29
  • Agreed, probably should revert back to previous kernel version until 4.15.0-24 issues are resolved or next kernel version is released. – SudoSURoot Jul 06 '18 at 00:18
  • Run shutdown. Wait about 30 seconds. Hold power key down for 10 seconds to power off. Press power key to start up. Login. Open /var/log/syslog or /var/log/syslog.1 and locate time of failed shutdown. Copy the lines into your question. – WinEunuuchs2Unix Jul 06 '18 at 22:58
  • @SudoSURoot based on comments OP posted under my answer I owe you a dollar :) – WinEunuuchs2Unix Jul 06 '18 at 22:58
  • The problem with this post though, if you check edit history and look at the first edit, is that the OP never said it was a kernel update (updating my Ubuntu), so we all assumed it was kernel update after someone edited it to say so, especially because of the many 4.15.0-24 issues. So, we really need to know more about what OP meant by, updating my Ubuntu, to know what was done and what could be the problem. – SudoSURoot Jul 07 '18 at 23:49

Just as a hunch I'm adding your question to last 24 hours of problems:

If you're suffering the same as the rest the same answer applies:

  • Reboot
  • At grub menu select Advanced Options
  • Pick an earlier kernel to boot with
  • Monitor this site for bug reports and fixes
  • Wait for 4.15.0-25 to be released and carefully test it

In your case reboot and shutdown are broken so close all applications and do 10 second power button press.
