bpusb.sys seems to call always null pointer address when shutdown.

[南昭弥]

Windows XP 32bit driver bpusb.sys (7.5.1007.26)seems to call always null pointer address when shutdown.

I always had BSoD and get Crash Dump when Windows Shutdown final faze.

CrashDump

SYMBOL_STACK_INDEX: 17

ae0e915a 5d pop ebp

SYMBOL_NAME: bpusb+315a

IMAGE_NAME: bpusb.sys

BUCKET_ID: WRONG_SYMBOLS

I disassembled it.

bpusb.sys

SUB_L00013140:

mov edi,edi

push ebp

mov ebp,esp

mov eax,[ebp+0Ch]

push eax

mov ecx,[ebp+08h]

push ecx

mov edx,[L0001E0C8]

push edx

call [L0001DB30] <- Crashed

pop ebp

retn 0008h

It is Intel Wimax Link 5050 Series Function Driver.

It seems Address 0001DB30 is alwasy zero.

I tried to change the following code with hand assemble.

Changed code

SUB_L00013140:

retn 0008h

I felt the BSoD is disappeared.

Hello blackwingcat,

Thank you for your collaboration to Intel Communities.

The options available for this issue are very limited.
