Bug Description
I cannot make a MacBookPro 11,1 suspend. When putting the lid down, acpi_listen prints:
button/lid LID close
button/lid LID open
... so the lid is signalling correctly. Upon opening, the screensaver prompt is present, and typing in the password brings me back to the desktop. Nothing is found in dmesg.
When choosing "suspend" from the top-right power menu, the screen goes black and shortly lights up again, showing the screensaver login prompt. Typing in the password brings me back to the desktop as if nothing had happened.
To remark that the power menu in the System Settings shows sometimes "Suspend" as greyed out.
WORKAROUND: Disabling wakeup from USB (the XHC1 setting) resulted in multiple sleep/resume cycles working flawlessly.

Further info: turns out that the system is running without swap space:
$ sudo blkid the-UUID- here>" TYPE="ext4"
/dev/sda2: UUID="<
... lists only one, when it shoud list also the swap partition. So:
$ sudo swapon -a cryptswap1: stat failed: No such file or directory
swapon: /dev/mapper/
The /etc/fstab lists the swap partition under /dev/mapper/ cryptswap1. While I never chose to encrypt swap, during the installation I did choose to encrypt my home directory. Perhaps the installer encrypted swap as well, and that is creating the problem with the lack of suspend and hibernate.
Attempting to run "sudo swapon -U <UUID>" fails as well. I used the UUID listed in a comment in fstab.
Any specific solutions to this problem? Perhaps this would solve the suspend/hibernate as well.
Thank you.
