New Revision: 233053
URL: http://svn.freebsd.org/changeset/base/233053

Log:
  Fix a couple of debugging outputs.
  
  * printf -> device_printf
  * print the buffer pointer and sequence number for any buffer that wasn't
    correctly tidied up before it was freed.  This is to aid in some
    current SMP TX debugging stalls.
