Ubuntu – Ubuntu 20.04 LTS locks up in shutdown (UEFI)

20.04freezelenovorebootshutdown

If I shutdown my Laptop (Lenovo ideapad 100) it freezes and won't shut down. I also have this problem in other distros like Deepin or Debian.

I've take me some time and googled about it.

I have tried to edit the grub file and replaced "quiet splash" with "quiet splash acpi=force". Doesn't Work.

Results from command sudo journalctl -b -1 -e:

I don't know what's wrong with that. It's just freezing and doesn't completely shut down

what @nobody try to fix it

  • disable ondemand.service #in debian I have not such service
  • add mds=full bootoption #because of MDS CPU bug present and SMT on, data leak possible
  • disable wake on lan #in uefi

Note my Sytems boot in bios mode (legacy only in uefi); my kernel is 5.4 kerneltree, not hw stack.

nobody's dmesg

There seem to be a number of reasons for Ubuntu not to complete shutdown. As examples:

  1. Encrypted swap.
  2. Bug #1464917.
  3. CMOS corruption.

There seem to be also a number of things you can try. As examples:

  1. Waiting for 35 minutes after shutdown, in case a timeout of 30 minutes is in place. Then, execute sudo journalctl -b -1 -e as you did (it is not clear if you did wait for the 35 minutes).
    Post in the question the results.
  2. This solution (no need to copy entirely here since it is in askubuntu)
    sudo swapoff -a prior to shutdown.
    Post in the question the results.
  3. Post in the question a screen capture or photo of the point where the system freezes.
  4. This solution (no need to copy here since it is in askubuntu).
  5. Check if swap is encrypted:
    If swapon --summary returns a description line for the swap, then it is encrypted, if it returns only the header line, then it is not.
    If sudo blkid | grep swap returns a description of the swap, then it is encrypted.
    Post in the question the results.
  6. Using GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" in grub (ref).
    Post in the question the results.

Additional information would be useful for you to Post:

  1. uname -a
  2. What ways are you using to shutdown?

As per the output you show, and comparing to this, it appears that swap encryption may be the cause. I will wait until you post the extra info mentioned above (see "Post..." above).
