How can I solve this Error (ATTEMPTED_SWITCH_FROM_DPC) ?

Hi…all.
I??m making a intermediate driver that is attatched to serial.sys.
And I have a fatal error like this.

#define ATTEMPTED_SWITCH_FROM_DPC ((ULONG)0x000000B8L)
A wait operation, attach process, or yield was attempted from a DPC
routine.

What I want say to you that I didn??t use a DPC Object and DPC routine
in my driver.
However that error can be happened?
I can??t find any detail explainaiton about ATTEMPTED_SWITCH_FROM_DPC
in DDK Documentation.

Please suggest to me any idea.
Thank for reading me.
Bye.
