Strange error message during kernel execution: "No kernel updates in a while..."

Hi all,

I'm observing a strange error message during kernel execution on nallatech-pcie385n-d5

"No kernel updates in a while... a kernel may be hung"
It comes with a list of kernels (kernel1, kernel2, ...) and some info on global mem accesses.

Has anyone seen this before? If yes, any ideas on what might be the cause?
What bothers me is that it seems to be random: I do not always get it and when I do it does not happen at the same video frame.

Any feedback would be appreciated.

Thanks.
