Hm, the NULL bio->bi_io_vec on unmount seems picky as to when it wants
to be reproduced, half a day bisecting on a spare system without
result...

I got it on one system with -rc1, on spare system a bisect
v2.6.30..v2.6.31-rc1 was always good. Will have to retry with complete,
not simplified config on one of the two systems where I got that trace.

FYI: someone else did report it on 2.6.30-gentoo-r4 which is
similar to 2.6.30.x, see http://bugs.gentoo.org/show_bug.cgi?id=281929
