[Pm-utils] pm-hibernate on a Lenovo T431s

[Tomas Davidek]

Dear all,
     I got a new laptop Lenovo T431s and I am fighting a lot with 
hibernation.

When trying simply pm-hibernate from text console, the system apparently 
saves the image to swap and powers off. That's ok. But when booting 
again, the last message on the screen is
Booting the kernel.
Loading, please wait...

I expected more info, since I set PM_DEBUG="true" in 
/etc/pm/config.d/01_debug.conf

Anyway, looking in the log (/var/log/pm-suspend.log) there are thousands 
of messages, it finishes with:
+ inhibited
+ [ -f /var/run/pm-utils/pm-suspend/storage/inhibit ]
+ return 0
+ date
+ log Fri Nov  1 12:19:11 CET 2013: performing hibernate
+ is_set true
+ return 0
+ local fmt=%s\n
+ [ Fri Nov  1 12:19:11 CET 2013: performing hibernate = -n ]
+ printf %s\n Fri Nov  1 12:19:11 CET 2013: performing hibernate
Fri Nov  1 12:19:11 CET 2013: performing hibernate
+ sync
+ do_hibernate
+ [ -n  ]
+ echo -n disk

Sounds like there is no message from the resume process? GRUB is set 
with resume:swap=/dev/sda7, so this should be ok too....

This has been obtained with purely pm-utils,  without hibernate & 
uswsusp installed. I also tried with uswsusp installed, the behaviour is 
similar, the resume process hangs at similar message
resume: image successfully loaded

Frankly speaking, I don't understand the interplay between pm-utils and 
swsusp, I thought these are different front-ends?

Thanks a lot for any hint in advance,

cheers,
                   Tomas
