I'm on a Lenovo ThinkPad W510, using Debian Squeeze but with the Kernel and acpi-related packages from testing (this was necessary to make hibernate work in the first place).

When I hibernate my laptop (suspend to disk) and try to wake (resume) it, about half of the time resume fails halfway through and the computer just reboots.

Here's my /var/log/pm-suspend.log after one such failed hibernate/resume cycle: http://dl.dropbox.com/u/5358991/pm-suspend.log

I'm not savvy enough to make much sense of it on my own, maybe somebody can?

Actual excerpt of /var/log/syslog after such reboot would be helpful –  barti_ddu Jun 2 '11 at 19:19
    
Where on that page does it indicate that one should install the acpi packages from testing? –  A Student at a University Sep 28 '11 at 15:37

Does this work?

When I installed the 2.6.38bpo kernel it wanted to change the /dev/sda2 I had
in /etc/initramfs-tools/conf.d/resume to ...
RESUME=UUID=<swap uuid> 
(no quotes)

 

In /etc/default/grub:
GRUB_CMDLINE_LINUX="resume=UUID=<number of swap partition>"  
$ update-initramfs -u
