Sorry; I wasn't able to reproduce the crash, with or without gdb.  And
I have subsequently disabled mbim in MM (crept back in, should have been off 
anyway).

The occasional crash at shutdown is still happening too; I'm afraid I don't
have any insight into that either.  But hopefully I can share my bridge
mode stuff soon.
