When I enable EHCI debugging (level 99) this does not happen
and between the debug output, I see:
Hi,
I think that the problem is not USB related, but it happens at a
point in time
where the UMASS USB transfer is half-setup. When the UMASS poll
callback is
called at the wrong time, then you will get a NULL pointer access.
Try the
following patch and report back:

No change.
