 Appendix:
 
 I tried with BusLogic Parallel (FreeBSD-32bit), LSI Logic Parallel and LSI 
 Logic SAS (both FreeBSD-64bit). The problem remains (I hope that was what 
 you ment with "try using a different storage controller").
 
 But what is interesting (and makes me think that the controller is not to 
 blame):
 
 I re-partition the disk using gpart:
 
 mfsbsd# gpart show da1

 I now copy ~30GB of data (actually a clone of a running system using vdisks) 
 to those partitons except for the designated / partition (da1p2). The system 
 does *not* panic. (I used rsync to push the data from the live system if it 
 is worth to mention it)

 But as soon as I rsync/dump/cp the / partition the panic occurs. Reliable.
