below is the specs:

Desktop:alienware-aurora-r6 Ubuntu 16.04.3 Kernel: 4.10.0-32-generic

I am able to reboot the system but I am not able to shut it down. The system hangs with the following error messages until I press my power button. Please refer to the attached image of the screen shot.

Kernel panic - not syncing: Fatal Exception in interrupt

Any advice on how to solve this would be appreciated. Thanks.

  • Confirm that intel-microcode is installed... dpkg -l intel-microcode | grep ii. Also, describe your SSD/HDD configuration. If SSD, describe make/model #. – heynnema Aug 16 '17 at 14:32
  • @heynnema Thanks for the comments. I ran the dpkg command and no packages found matching intel-microcode. Disk config is 256 PCIe SSD (system) + 1TB SATA HDD (storage). Not able to retrieve info for SSD seems ubuntu cannot recognize the brand and model. Weird. System running okay on SSD. – Ethan Aug 18 '17 at 01:36
  • Since you have Intel processors, install intel-microcode with sudo apt-get update and sudo apt-get install intel-microcode. Use sudo lshw -C disk and see if it'll tell you about the SSD... at lease the model #, and maybe the manufacturer... then go to the manufacturer's web site and check for updated firmware... very important. You should also check for an updated BIOS for your computer. – heynnema Aug 18 '17 at 01:50
  • @heynnema Thanks. I installed the microcode and lshw only shows my 1T Seagate HDD. I tried sudo parted -l, it shows the SSD but model unknown with only a serial number (only numbers cannot figure out brand). I will try other ways to figure out the SSD model. Unfortunately I dont have a windows on my machine. Thanks. – Ethan Aug 18 '17 at 01:57
  • Is this a desktop machine? Is the 256 PCIe SSD visible that you can find a make/model # on it? – heynnema Aug 18 '17 at 02:06
  • @heynnema ya is Dell desktop. I found the SSD model from Dell website and its SanDisk A400. I guess it is visible by ubuntu since I installed the ubuntu on this SSD and sudo parted -l can see it. But Ubuntu can not detect the model of the SSD and it is shown unknown model. – Ethan Aug 18 '17 at 02:29
  • but lshw cannot see the SSD i have no idea why. Is it because it's the system partition? – Ethan Aug 18 '17 at 02:31
  • It can't see it because it's PCIe. Now take that make/model # over to the SanDisk web site and find out if there's a firmware update for it. Do the same for your BIOS. – heynnema Aug 18 '17 at 04:11
