XDMA driver win10 run well, Win7 BSOD

hi, I built the driver with code xdma_driver_win_2018_2 separately for win10X64, win10X86, win7X64,win7X86, that work well in Win10 , but both win7X86 and win7X64 BSOD after run while.

I write a demo to read and write dma channel continuously and user interrupt act occasionally, win10 ok.

On win7, it will BSOD when a dma interrupt and  user interrupt arrived same time.Not every time but must in several minutes.

All the drive built with KMDF1.11,

Legacy interrupt and user interrupt used in XDMA.

Thanks for any help or investion guide.
