I don't think SMP would do it, although it's possible.  I just noticed that
even though the 5.5 machines I found were using an SMP kernel, hw.ncpu=1
for them all.

More probable is that there were 5.5 bugs which were fixed by 5.5-p8.
Maybe you want to give that a try?  I will certainly ask around here if
anyone had to do anything special to get things to work.

Sure, but maybe arla doesn't handle that case well.  I know that arla had
some various bugs in the past; without a more detailed message, I can't say
for sure what happened.

I certainly hope someone can futz around with getting arla to work with the
post-nerfed VFS changes in 6.x.  Maybe that same person would be willing to
help me get HFS+ working too.  I gave up on both these projects because the
APIs kept shifting while I was trying to get them to work, and I just don't
have the time to relearn everything and familiarize myself with the new
locking mechanisms.
