 I am using only vanilla FFSv2. The root partition is located at an 
 internal raid (scsi, controller perc 5i), some other partitions up to a 
 size of 3 TB are located on external storages (scsi, controller perc 4e). 
 Quota is enabled at some partitions.
 
 The crash results in an automatic reboot. So I get only a trace if I set 
 ddb.onpanic=1. I will attach a new trace from last night:
