Not exactly:
fk@TP51 ~ $grep +++ ~/test/combi.patch | wc -l
38

I got the same panic with /usr mounted rewritable
and both directories on the same file system this time.
Running patch -p1 < ~/test/combi.patch seems to be
enough to trigger the panic.
I tried three runs with a smaller patch (unionfs6-p11.diff)
without panic, I then took the bigger patch again and
a few seconds later the system panicked.

I'm not sure anymore if I used the same patch the first times.
