Comment:

 if i revert 3517a0561e15c68734bb9dc59405030f66450a23, i can no longer lock
 the system (either with or without X) with simple suspend/resume cycles.
 (the two 'count' args to memcpy_fromio() seem odd.)

 i _can_ still lock the system as in #9581.

 i _can_ still lock the system as in #9420.  the difference in that case
 (in my testing -- i can't really speak for cjb) is that the i reproduce
 #9420 with a loop:
 {{{
     while :
     do
        echo mem > /sys/power/state
     done
 }}}

 whereas this bug i reproduce by hand.   my suspicion lies in the fact that
 the console session is terminated and restarted across the suspend/resume.
 the loop which reproduces #9420 attempts to keep running across the s/r
 cycles.  do we understand why the console session restarts?
