Wolfgang, I had something similar happing on my system at home w/ an ADIC scalar 220. I remember thinking that it was strange that btape and other utilities had not problem, but bacula was causing huge problems. I traced the error down to what I thought was the st driver in the 2.6.14 kernel.. In the end, upgrading to 2.6.15 solved the problem. Are you by chance running 2.6.14? If you are and you upgrade to 2.6.15, make sure to turn on the new 'SCSI media changer support' option if you use an autochanger. This one had me stumped for nearly an hour trying to figure out why my changer had disappeared :)
