That sounds like a problem in DDB itself, probably arm32 port specific.

If no filesystems have been setup for softupdates, the softdep code should
not get called ever. So "options SOFTDEP" won't have any effect at that
Problems in the softdep code are currently being tracked down, and
thanks to the efforts of Greg Oster who could quickly reproduce problems
using raidframe, a few likely problems have been identified. I'll send
a message to this list when I think they're fixed, so that you can
try again should you have problems with the softdep code at the moment.
