[SI-LIST] Question about AC coupling caps on SATA lines

I had a system that had two AC coupling caps at both the transmitter and
receiver, so a section of the line was floating as far as DC goes. I was
having some problems so I replaced one of the caps with a short and think
it helped. I have run into that situation again and wondering if having a
part of the SATA line floating w.r.t. DC can be a problem. Seems to me it
could.
Thanks - Joel
