I think I could reproduce your problem, or something like your problem.
On my test machine with test-kernel without aufs, rosegarden shows an
error dialog window, saying "rosegardensequencer crashed and caused
SIGABORT". Closing similar dialog windows several times, rosegarden is
up. Though I don't know how to operate it.
Additionally the network(sis190) stopped. I don't know why. There MAY be
some conflicts between sis190 and patch-2.6.29.4-rt19. The system is
fine eccept the network.

On the kernel with aufs, I could see some tasks entirely stopped around
RT locks related to aufs.
Finally here is a new patch for you. Revert the aufs2-rt13-29.3.patch
and apply this.

To be honest, I don't know how to support RT patches. In aufs1 era, I
chose the 'compat_rw_semaphore' way which MAY lose the realtime-ness in
aufs. By the aufs2-rt13-29.3.patch, I chose the 'RT rw_semaphore' way
which MAY keep the realtime-ness in aufs. In both way, I am unsure.
By reverting aufs2-rt13-29.3 and applying this new patch, aufs2 will
take the 'compat_rw_semaphore' way. With this patch, I could see my test
system runs well, except the known error dialog and network problems.

And I will fix the "mount -f" messages in next Monday release.
