Bug Description

Until recently, hibernate worked on my Dell XPS 13 Developer Edition (the production model sold starting in late November 2012). After recent updates, it no longer works. Choosing Hibernate from the shutdown menu seems to hibernate, but pressing the power button to resume from hibernate just boots the computer normally. i.e., the hibernated state is gone.

There are some kernel warnings briefly visible on the screen while hibernating. I'll try and memorize them and add them here.

It was something like:

legacy_resume: pnp_bus_resume returns -19
Device failed to thaw

Note that the kernel warning also appears for suspend, but suspend works. So it's probably a red herring.

The initramfs config does specify the correct resume device:

$ cat /etc/initramfs-tools/conf.d/resume
RESUME=UUID=57326aa8-1fdf-45d9-a93d-6ce52a4d9e81
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/zram0 partition 3866224 0 100
/dev/sda5 partition 15871996 0 -1
$ sudo blkid /dev/sda5
/dev/sda5: UUID="57326aa8-1fdf-45d9-a93d-6ce52a4d9e81" TYPE="swap"
$

I can't figure out what's wrong. :/
