My speculated cause might be wrong, as it seems to not be resuming
consistently again.  This happens most often when I switch power states
while the machine is suspend to RAM (e.g., detach the power cord and
resume).  If it doesn't resume properly, I can get it to resume by
plugging it in and unplugging it until it resumes (usually after doing
this 2 or 3 times).  If I just leave the machine when it is in this
state, it will not resume by itself.

Occasionally after forcing a resume by the power cycling method, I get
messages like the following in an open terminal:
