bad: scheduling while atomic! ???

The story is...
I am testing a device, the device driver acts fine under the console mode test application.
But for UI test program , i use the same ioctrl function as console mode after
clicking a button, it always replies : "bad: scheduling while atomic!"

Is there any difference for calling device driver operation under console mode and X mode?

I am quite confused...
Please give me a hand , ok?

There shouldn't be a difference. There may be something, however, if the device is used by X (like a graphic card). If it's not the case it looks like a bug in the driver (maybe a timing problem).
