Hi,
I downloaded the source through mercurial and did a make on Ubuntu 9.04.
There were no compile errors. I followed the readme and installed the modules.
I booted my system with mem=512M.

Is there anything I am missing??
Looks like you have another swap device which has priority higher than ramzswap.I downloaded the source through mercurial and did a make on Ubuntu 9.04.

Check with: cat /proc/swaps
It will show active swaps and their priority.
To set highest priority for ramzswap, do:
swapon /dev/ramzswap0 -p 10
('10' is the priority -- use any number higher than priority of any existing swaps)
As a side note: always reset ramzswap device after you do swapoff:
swapoff /dev/ramzswap0; rzscontrol /dev/ramzswap0 --reset
Thanks,
