Hi Arnaud,

Just to verify that you are testing on an MX51-Babbage board? Here's my log:

root@...escale ~$ uname -a
Linux freescale 2.6.38-rc1+ #93 Fri Mar 4 17:18:15 CST 2011 armv7l GNU/Linux
root@...escale ~$ echo mem > /sys/power/state
PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.01 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
Suspending console(s) (use no_console_suspend to debug)

<Press power key here, and the wake up is the bottom>.

PM: suspend of devices complete after 0.835 msecs
PM: suspend devices took 0.000 seconds
PM: late suspend of devices complete after 0.159 msecs
PM: early resume of devices complete after 0.187 msecs
PM: resume of devices complete after 81.911 msecs

Thanks,

Dinh
