UMDF crash when uninstall/disable

Hi all,

My UMDF driver crashes when it is being disabled or uninstalled.

Using Windbg, I got the following error:

ntdll!NtWaitForWorkViaWorkerFactory+0xa:
00000000`772317ba c3 ret

When I used !analyze -v command, it only shows the following info:

Last event: 13dc.12b4: Exit process 0:13dc, code 70000003
debugger time: Sun Jun 6 16:35:05.808 2010 (UTC + 8:00)

Then I dump the thread info:

.. 1 Id: 13dc.12b4 Suspend: -1 Teb: 000007ff`fffdc000 Unfrozen
Start: ntdll!TppWorkerThread (00000000`771f8f00)
Priority: 0 Priority class: 32 Affinity: 3

Here is the teb:

My question:
1. Where is this WaitForWorkViaWorkerFactory came from? Is it called by the
framework?
2. How do I find which worker thread is calling this? I can only get the id
of the thread (12b4, in this example), but I can't trace it back to any of my
code.
3. What is code 70000003?
4. In TEB, the last status shows INVALID_PARAMETER. How do I find which
function call got invalid parameter?

Thanks for the help.

G.

Can anyone help?

Thanks.
