Some more errors; <http://home.komsys.org/~jocke/dmesg_mps0_freebsd-scsi_3.txt

just because I increased the number, so that this specific error- 
message isn't printed?).

This happened without direct user-interaction (it's a cron-job that  
copies files from 'zroot' to 'storage', and deletes some stuff on  
'zroot' afterwards). However, it seems as if I can access the files/ 
folders on 'storage' without the terminal freezing (based on the log- 
messages, I was able to pinpoint the last 2-3 copied folders, and  
those I could list/copy files from without the terminal freezing). I'm  
not sure why, though. Maybe because the error/crash occurred when no  
files where being copied/moved?
