 I hadn't -- should I have?  It does seem to prevent the problem; at
 least, I wasn't able to cause any crashes when I tried that.  (To be
 sure, I got another crash when I shut down the machine to try that
 test; I haven't looked at that dump yet....)
 
 For now, I'm going to put a cpuctl in my suspend/resume scripts -- it
 had reached the point where I was shutting down rather than risking a
 second suspend.
