I'm getting this error. My suspicion is that _something_ is

The general behavior is that I can launch my kernel, it will
finish, but I can't get my data back to the host. After doing
this several times the whole card seems to lock up and become
useless.I'll just keep investigating, but I thought I should
put this out there in case someone else sees the same problem.
Did you find out what caused that bug?
I'm getting this every few executions. When I compile the same code
on the CPU in emulation mode and run it everything works flawlessly.
