Anyone else having problems with internal watchdog?

WATCHDOG: GPU 1 hangs in OpenCL call, exit
WATCHDOG: GPU 1 hangs in OpenCL call, exit

And it just stands there.. I need to manually reboot rig each time. It works for a day or two and then GPU hangs and it just stops. Why the watchdog doesn't reboot the rig when this happens? I mean it's still green in dashboard, so just one click is required, but why it doesn't reboot itself without clicking?
