Hello Pavel,

the same I supposed. But in this case, there's an error somewhere: I can
never resume properly if I use 'echo disk > /sys/power/state' and I get
a kernel panic with these words:

Resuming from /dev/hda7
Resuming from unknown-block(3,7)
Kernel panic - not syncing: Resume Machine: Unable to find
suspending-data signature (pmdisk-swa - mispelled?

Usually, my lilo is configured to append 'resume=/dev/hda7' and I tried
even at boot with 'pmdisk=/dev/hda7', but it doesn't matter. So probably
the code is different in the 2 cases. Can someone check, please? I
suppose the /sys call is better, as all the /proc fs is being ported to
/sys, am I right?

On the other hand, using the /sys call the machine power off correctly
in suspending, while using the /proc call actually I should press 4-sec
the power button after 15-20sec the latest suspending screen.

BTW, I'm on 2.6.9-rc2 with no other patches.

Thx, bye,
Gismo / Luca
