 Thanks for the quick reply.  I decided to do a fresh install of
 8.0-RELEASE amd64 before I re-ran the test.  Here are the details:

 I believe the problem occurs whenever you see a message like this:
 Nov 23 14:57:16 lab1 kernel: ucom_get_data:1064: cnt=64
 
 >From a look at the code it looks like the largest uftdi frame is 64 characters (UFTDI_[IO]BUFSIZE in uftdi.c).  Perhaps it is an off by one bug?
