NMI watchdog: BUG: soft lockup - CPU#2 stuck for 23s! [nvidia-smi:566]
I installed Xubuntu xfce 16.04, everything was fine, the boot time was about 10 sec, but I could not play games. Then I installed nvidia drivers (I have GTX950, and monitor 2560x1080), it would only boot on recovery mode (just entered and resumed). So I made this modification on grub:
/etc/default/grub
GRUB_GFXPAYLOAD_LINUX="keep"
GRUB_GFXMODE="1920x1080x32"
After that, it boots, but it takes so much time... the screen freezes at the line:
Starting File System Check on /dev/disk/by-uuid/d6e1f5fa-e0e8-455f-8888-268ce02d3a9d...
Starting File System Check on /dev/disk/by-uuid/322B-518B...
[OK] Started File System Check Daemon to report status.
_
After about 25sec I got a Beep sound, then it resumes and the login screen shows up. I have no problem after that.
Below is the journalctl:

This is my fstab, I copied the entry for the root /, and replace "/" for the "/media/wilhovisk/SSD-silver-cloud", maybe there is too much space after the mount point. Can I delete the spaces and hit one time tab key?

How can this be solved? I can post other reports here, just say what I have to post that can be useful to resolve this bug.
Thank you.
Here is what solved it for me: I saw this post on Linux Mint Forums and followed the advice of Laurent85:
At startup edit the Grub menu entry and append kernel parameter
nomodesetormodprobe.blacklist=nouveauto existing parametersquiet splash".
So I edited the file /etc/default/grub, and edited the GRUB_CMDLINE_LINUX_DEFAULT line to this
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset".
Afterwards I ran sudo update-grub. Thats it, 8 seconds the boot time, no beep sound, I am so happy, no CPU stuck on journalctl anymore! :)
Warning! Adding nomodeset permanently to /etc/default/grub will disable Nvidia drivers. This option is useful only if the system doesn't boot correctly with nouveau. After you install Nvidia drivers, this parameter should be removed.
I had the same problem on a fresh install of Ubuntu 16.04 with an Nvidia 8400 GS card. after I installed the recommended, tested, proprietary Nvidia driver v.340-104. via Additional Drivers. My solution begins with a similar approach as [this answer] but ends somewhat differently.
1) At startup edit the Grub menu entry and append kernel parameter nomodeset to existing parameters quiet splash.
2) Revert back to the nouveau driver via Additional drivers.
Note: If you installed nvidia drivers via some other method you may need to purge them following steps 1 and 2 here skipping the line blacklist nouveau in step 1.
3) Reboot.
Boot time is respectable for an old Intel E6500 Dual Core without an SSD.
