New Revision: 223608
URL: http://svn.freebsd.org/changeset/base/223608

Log:
  Disable microcode loading for 82550 and 82550C controllers. Loading
  the microcode caused SCB timeouts. Linux driver does not allow
  microcode loading for these controllers and jfv also confirmed that
  there is no need to do and it shouldn't.
  
  PR:				kern/103332
  Additional confirmation from:	jfv
  MFC after:			1 week
