在AddDevice出现BSOD了....

  小弟主要是想送ACPI Command，由BIOS用ASL Code定义一个PnP Device

然后再去驱动去，由Device Stack把ACPI command送给pdo

但装完我的Driver后，开机就会有BSOD(XP SP2 DDK June 2006)了....Error Code 19-->BAD_POOL_HEADER

AddDevice的code如下，请各位大大救救我...，也有试过自订DeviceName不过之前的Driver

移除后，在Obj Manager里还是看得到之前建的Device，第二次执行就会出现名称冲突了...

请各位大大救救我
