How to test suspend ?

How to test suspend ?

[Giuliano Pochini]

I couldn't make s2ram work on my machine and /sys/pci/.../power/state
virtual files were removed one year ago. How can I test suspend/resume ?

$ cat /sys/power/state

^^^^ nothing.

Cat does nothing because it doesn't change the current state.  It should return:

standby mem disk

if the kernel is built to handle power management.  If it does return
any of these values, to change state you would type (as root):
echo mem >/sys/power/state   # suspend to ram
# or
echo disk >/sys/power/state     # suspend to disk (hibernate).

It is... and /sys/power/state is supposed to be "mem" only. But since it
doesn't work, is there another way to test suspend/resume of the soundcard ?
