It appears, somehow, that softdeps have been turned on for this filesystem!?!? If you turn off softdeps does the problem go away?
To answer your question more accuratly than my last post: yes, turning off softdeps helps indeed. I've tested again, same system, but already running this time. I could mount the same partition with rw, log, noatime and read and write from/to it. But after mounting with log+softdep (the combination is important, as both are fine when used alone!), the system panicked again. The slightly different panic and more from ddb(4) at: http://nerdbynature.de/bits/PR-39875/
Thanks, Christian.
