Bug Description

Well, I have 512 MB of RAM, and 530 MB of Swap. I have changed the swappiness to 10, so my swap when I hibernate the first time is clean, all free. When I resume from it, I get the swap partially occupied, and I dont understand why, if before I hibernate it, it was clean.

Is this a bug? Im usign Breezy.

Thanks in advance.

I don't think this is a bug on the hibernate package (unless you have it installed). This is probably a bug on acpi-support or kernel-source-2.6.15.

Still, the way ubuntu hibernates is that it effectively swaps everything out to the swap file and tweaks a bit to tell it to be a hibernate file, so when the next boot occurs, the kernel knows to restore from the swap partition. The swap partition is reset from hibernate mode to swap mode, and the memory pages are loaded in. But only the memory pages required to get the system back up will be pulled out of the swap partition.

Dapper 6.06: on a Dell Latitude D600 I can well hibernate once,
but not twice. On the second attempt the system just doesn't
start to hibernate.

For a laptop I consider this as a major problem because a laptop
is often used (e.g. on travel) for short moments between which
one doesn't want to restart the whole system and apps.
