I have determined that after the resume, the controller requires an 
extended period of time before it is ready for use.  The errors I was 
getting were due to the driver waiting for the busy bit in the status 
register to clear, and it did not before the wait timed out.  I worked 
around the problem by extending the timeout by a factor of 100, but this 
does not seem like an appropriate fix.

Is there maybe a method in the DSDT that is called during resume where I 
could make it wait for the controller to be ready?
