There are no Can you tell me *exactly* what your tape drive is reported as? (dmesg is useful here) Also send the results of `mt status' after a boot *before* you do anything with the drive. I had what I believe to be the same problem when I moved to current. I discovered the code for detecting the particular device (archive viper) in the "know quirks" list was broken. I fixed it...for my drive but apparently not for yours. Among other things, when properly detected, the quirk list sets useful defaults for the density. If it is indeed this problem, you can temporarily get around this by setting the density manually.
