 |
|
I have a 1GB swap partition and about 500-600 MB of RAM currently in use. When I try to suspend to disk, the screen goes blank and after about a minute the system goes back up. After that gkrellm shows ~350 MB of RAM and ~700 MB of swap used. After I do a swapoff and swapon, it returns to the initial ~500MB RAM usage. dmesg shows something like this: | Code: | [18358.967586] PM: Marking nosave pages: 000000000009e000 - 0000000000100000

Why does it say "PM: Not enough free swap" when I have almost double the amount of needed space? |

Well, it says it wants ~1.5G of space, and on the whole I'd believe it. Why?
That I don't know.
