After all of this mess with people having problems like this, yours is the first I've heard from using a Belkin Dock. I'm also using a Belkin Dock, but not your model (I'm using this one). I've found better stability using my Monitor's HDMI instead of the Display Port. I was having more issues with random reboots (although not as much as what you're saying) when I used DP out to DP in. I switched to using the DisplayPort out to my Monitor's HDMI in (cable has DP on one end and HDMI on the other) and now only seem to get random kernel panics when I reboot.
Have you submitted feedback in the app from your Mac? Explain what model dock you have and maybe even include a link to the product website. They're obviously aware and are trying to work on the issue, but clearly have a ways to go.
