No

EHCI to xxx_pc_flush() and xxx_pc_invalidate().
Probaby you see more on your AT91 device as you know USB stack
internals.
Have you tried to bring up OHCI on you ARM board ?
Not yet. I'm terribly busy with some LibUSB stuff headed for the 8-
current
release. As soon as I find time I will fire off a build and debug.
Please note these problems should be considered as a showstopper for
the release since USB is currently broken on at least three ARM
platforms in the tree (Marvell).
BTW: Has pmap been fixed for ARM in 8-current?
Seems like the most critical problems (panics) are resolved and will
be pushed into SVN shortly. In case you'd like to apply the fix
directly, see: http://people.freebsd.org/~raj/patches/arm/pmap-fixes.diff
