I spoke too soon. Depending on what I do in userland (I tried using the
GNOME application "Cheese" just to put some load on the machine) and I
tried:

# echo shutdown > /sys/power/disk
# echo disk > /sys/power/state

But the machine stuck: it blanked the monitor, seemed to go to a console,
the cursor was blinking on the upper left corner of the screen, the HD
light blinked once and then the fan went faster, the CPU hotter and the
leds corresponding to caps lock and scroll lock were blinking.

I'm waiting with the machine in this situation since I started composing
this e-mail and nothing has changed.

The blinking leds (caps and scroll lock) would indicate a kernel panic, is
that correct?

The funny thing is that once that I could resume, it resumed
instantly. :-( Weird.

Thanks, Rogério Brito.
