[wdmaudiodev] Possible problem in IPortDMus::Notify and servicegroup dispatching?

Hi again,
I have been able to create a crash-dump with my problem using the
<CrashOnCtrlScroll>
method.
When running my driver with verifier active, the freeze does not show up, I
guess the
timing being really tight is important to reproduce the effect (thats also
the reason
why my checked build will not freeze, but runs for hours and hours!)
This time I held no locks whatsoever in my capture-path, no events arrived
on my
render-path during the test - still the system froze after a couple of
seconds...
After analyzing this dump, I think I found an issue in the way Windows XP
handles
IPortDMus::Notify and dispatching the DPCs to the capture-stream's
service-group on
SMP systems. (Possibly something to do with multiple locks being acquired
in the
wrong order???)
I have found one similar topic here on the list from Art Edwards
("Driver-Verifier-Deadlock-on-x64-System), but he did not get
any response....
So any pointers would be highly welcome ;-)
Here is what windbg told me:
