Hm.  sudo lvdisplay lvmvolume shows that I have 2.0 GB allocated to
/dev/lvmvolume/swap.  And the machine has 2.2 GB of RAM.  I don't think it's
a compression issue.  I could expand the swap logical drive if that would
help.

I've also never used LVM so I don't know any gotchas with uswsusp there.


I only know enough about LVM to be really dangerous.
