Eric sent me this patch:
http://www.googlebit.com/freebsd/patches/ffs_softdep.c-patch
which seems to be working great so far. I am still testing it, but I
think it fixed the problem.
To apply, cd /usr/src; patch < /path/to/patch and then rebuild the
kernel.

Cheers,
Pieter de Goeje

It doesn't actually 'fix' the problem, but I think it helps identify it.
I'm not 100% certain if this is the right fix our not, but so far
feedback has been good when running with this patch.

Can somebody confirm that this patch is ok?

Eric
Can you elaborate on what this patch exactly does / what the problem is?

Pieter
