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:
