           Summary: cinergy T2 on x86_64 produces "phantom" data, recalls
                    RC commands and RC has dysfunctional repeat buttons
           Product: v4l-dvb
           Version: unspecified
    Kernel Version: 2.6.32.x, 2.6.35.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dvb-core
        AssignedTo: v4l-dvb_dvb-core at kernel-bugs.osdl.org
        ReportedBy: kdevel at vogtner.de
        Regression: No


Differences of the device running attached to a computer running a 64 bit
kernel compared to the 32 bit version:

 - Volume control buttons "+" and "-" are not repeat buttons.

 - Some commands given from the remote control are recalled up to
   minutes after they've been issued and are then delivered to the
   application. This happens even if the device is dis-/reconnected.

 - With enabled debug output (cf. patch below) in cinergyT2-core.c the
   driver continuously outputs lines like these

cinergyT2: key: ed 41 be 3 0
cinergyT2: key: 72 73 8c 6d 65
cinergyT2: key: 64 65 9a 63 6f
cinergyT2: key: 75 64 9b 2f 63

   at a rate of about 16 per second to the system log.
