FBSD 2.2.2 tape problems!

We made backups of our serverdisks every week with the wangtek es5525 tape drive and anything ran well! When we migrated from FBSD 2.1.7.1 to 2.2.2 many problems occured! First I get a lot of error messages about command fails on our NCR 53C810 SCSI controler (sometimes the controler fails on sd0 or sd1 or sd5, disk 0, disk 1 and the cdrom respective). The problem with the controler is still present but sometimes the system boots and we can work. I tried to dilatate the delay-time, but that has had no effect! Then suddenly we lost our "primary partition table: no magic " on our data disk! That is a big problem. So We tried to reformat the disk with problems and then to replace the backup from the tape. But this seems to be impossible! We can not replace the backup from our tape back to the disk! We always get errors like /kernel: st0(ncr0:3:0): error code 0! What happened to the system? What is that new in the 2.2.2 kernel for the NCR controler that it isn't possible to replace tapes written with 2.1.7.1? Any kind of help is appreciated! O.
