Can't find the same problem on the internet and here. Hope somebody on this forum could help me out.

Here's the PROBLEM:

We've got HDSPe MADI card that is connected with TCO option card. Most of the time everything is ok - TCO chases the timecode (from LTC port) just fine. But... Every once in a while the TCO card hangs the whole system and shows timecode as 45:85:85:45 inside the RME drivers menu; timecode display blinks fast and is stuck at 45:85:85:45. Computer starts to show a very heavy processor load and works very slowly.

Unplugging timecode from LTC in doesn't help - after unplugging the LTC it still shows 45:85:85:45 in timecode block of RME drivers.

The only thing that helps is reboot.

Hope RME engineers could chime in and help us regarding this problem.
