- It may happen so, that the driver was loaded by the bootloader, but failed initialization (thus DriverObject == NULL), and later PNP manager tries to install it again, and BSOD due to NULL DriverObject (because really only its image is loaded, but it's not initialized). Prevent this situation by initializing DriverObject in that case.
