OK: The FBSD version was varying: R6.1, R6.1-CURRENT, R7-CURRENT.
But we just found out, that it happens when we use "newfs -b 65536", but not with default "-b" value (whatever that might be)...
So if somebody wants to reproduce it, he/she should use >R6 and "newfs -b 65536"...
I think that were all steps to do...
Can somebody reproduce it now?
DDB is not my bag, so that I would be glad, if somebody with an appropriate setting could reproduce it...
