Comment(by dsaxena):

 Replying to [comment:7 pgf]:
 > 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.)

 Yep, looks like a buglet, I'm copying 0xff fromio but writing back 0x100

 > 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?

 I've opened a separate bug for that issue, #9584
