Ubuntu – ‘Clearing orphaned inodes’ and state lost on hibernation resume


I installed a fresh 16.04 LTS. I have been experiencing some problems with Wifi applet display error (after resume from Suspend) and with hibernation resume. I enabled hibernation on menu using the method shown here . Now hibernation resume is not working intermittently. Sometimes it works fine, other times it displays text on resume that says something about 'clearing orphaned inodes' and the system simply boots up anew, without the prior memory state.

Here's some info:

$ sudo blkid
/dev/sda1: LABEL="System Reserved" UUID="50921EE4921ECE7A" TYPE="ntfs" PARTUUID="dda192f8-01"
/dev/sda2: LABEL="Primary Disk" UUID="765E305F5E3019F7" TYPE="ntfs" PARTUUID="dda192f8-02"
/dev/sda3: LABEL="Secondary Disk" UUID="E2D42C6AD42C42E1" TYPE="ntfs" PARTUUID="dda192f8-03"
/dev/sda5: UUID="dbaad068-46da-4637-9c45-5c32c20d3cfe" TYPE="swsuspend" PARTUUID="dda192f8-05"
/dev/sda6: UUID="31385b29-f351-4a10-9dcf-c92efd58334b" TYPE="swap" PARTUUID="dda192f8-06"
/dev/sda7: UUID="1f734f56-7328-4029-88a0-fa995426d4d2" TYPE="ext4" PARTUUID="dda192f8-07"

$ cat /etc/initramfs-tools/conf.d/resume

Well, I am surprised nobody suggested this as I have been having this problem for quite some time. The answer it seemed was staring right in my face. Apparently my swap partition was roughly the same size as my memory. Also, I hadn't added the link to my swap partition's UUID in my grub file. After increasing the swap partition size to double that of the memory and adding its UUID in the grub file the hibernation resume is working normally for the past few days. Although, the resume from hibernation takes a tad bit longer but I'm not complaining.

You need to make sure that your swap partition is defined in the following files:

  • /etc/initramfs-tools/conf.d/resume
  • /etc/default/grub


Using low level interface uswsusp as default hibernating mechanism drastically improved my resume time to under a minute !!!

sudo apt-get install uswsusp

Create file /etc/pm/config.d/00sleep_module and add following line:

  • SLEEP_MODULE="uswsusp"
