New description:

 The first power button press suspend after boot fails with

 {{{
 [  233.674476] dcon_freeze_store: 1
 [  233.690566] dcon_source_switch to DCON
 [  233.717190] olpc-dcon: The DCON has control
 [  233.872482] dcon_freeze_store: 1
 [  233.972578] dcon_freeze_store: 0
 [  233.975842] dcon_source_switch to CPU
 [  234.017524] olpc-dcon: The CPU has control
 [  241.943073] PM: Syncing filesystems ... done.
 [  242.031622] Freezing user space processes ...
 [  242.037883] Freezing of tasks aborted after 0.00 seconds (123 tasks
 refusing to freeze, wq_busy=0):
 [  242.046885]
 [  242.048431] Restarting tasks ... done.
 }}}

 and the system remains active.  Repeating the request works.
