I've got a Thinkpad T400 with Gentoo Linux installed. Suspend-to-RAM works like a charm.
However, Susped-to-Disk doesn't work: if I suspend, the Laptop powers down and accesses the HD for around 30s. However, if I switch it back on, it just boots as normal, but doesn't resume to the previous state.
Here's the /var/log/pm-suspend.log just before the suspend:

Sun Oct 21 15:26:08 CEST 2012: performing hibernate In the /var/log/syslog I found the following line:
Oct 21 15:27:10 lenovo kernel: PM: Hibernation image not present or could not be loaded. Here's my grub config:

What could be wrong?
