Crash driver on K2200


I have a driver issues with my code. I work with the Quadro K2200. The problem is the driver crash and freeze my Windows (I have to hard reset my PC) when I compute a glGenerateMipmap on a no-square texture in RGBA32F.
I expect the commande buffer is empty so the glGenerateMipmap start on the uncomputed texture. Il put a Sleep(500) between the glDraw and the glGenerateMipmap. It’s works but it’s so dirt!
I try to synchronize the GPU with the CPU with glFence, glFlush, glFinish, glBarrier and it still crash.
I don’t have any other idea to wait the and of the rendering.

Best regards,
