I have a Lenovo Thinkpad Edge 13 (Intel model)

I've gotten everything to work under Ubuntu except for hibernation. The system hibernates normally but when Ubuntu tries to boot from the hibernation file, it freezes.

I tried with the 2.6.35 kernel and the newer 2.6.36 (which solved my eating-battery problems), but this issue persists.

How could I troubleshoot this issue?

EDIT:

  • My Ubuntu install is in a separate partition alongside Windows 7.

    I've tried a BIOS update today, and the problem still persists.

    My swap partition is bigger than my installed Ram (2,3GB vs 2,0 GB)

Suspend as a sleep method works, but I really need my hibernation option.

can you provide us more information on how your ubuntu is installed; wubi? another work around is using standby –  myusuf3 Feb 26 '11 at 18:44
    
Is it really a freeze or does it only take unusually long like 10 min or so (I've seen that before)? –  Takkat Feb 26 '11 at 20:49
    
@dustyprogrammer I'll add the info in my question –  bruno077 Feb 26 '11 at 21:10
    
@Takkat it's a real freeze, the only way to recover the computer is my rebooting –  bruno077 Feb 26 '11 at 21:10

I'd recommend you open a new question about this issue giving detailed info about your hardwar. –  bruno077 Mar 23 '11 at 19:40

I would try a BIOS update as there seems to be some issues with power in the past. I have known BIOS updates to solve these issues. Try here.

Thank you, both for the info and the link; but BIOS update didn't solve the problem unfortunately =(, still looking for the solution –  bruno077 Mar 28 '11 at 19:27

There are often clues in /var/log/messages. Look for what the kernel said around the time of the crash or hibernate attempt.

You could do the following

  1. Update the bios
  2. Install the latest kernel
  3. Install the proprietary graphics driver

I fixed it. Turns out it was the package

uswsusp

which replaces the default hibernate and sleep methods, the one that was causing the freezing. I uninstalled it and reverted to the default Ubuntu hibernate and it works flawlessly.
