           Summary: fw-ohci: DV reception with dvgrab broken on VT630x in
                    OHCI 1.0 mode
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.22 and later
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: IEEE1394
        AssignedTo: drivers_ieee1394 at kernel-bugs.osdl.org
        ReportedBy: stefan-r-bz at s5r6.in-berlin.de


fw-ohci works incorrectly with VIA VT6306 and VT6307 if the controller EEPROM
programs them into OHCI 1.0 mode (most or all VT6306, many but not all VT6307):

DV reception with dvgrab stops after a few frames (one or two frames fro
example).  Curiously, reception with kino actually works.

Last tested:  libraw1394 from Dan Dennedy's git repo (revision
f9681ff59da0acca543ad5d15213c6253114f0ce from April 30 plus "Plug dir leak and
initialize data structs"), dvgrab 3.1, kino 1.3.0
