Scsi-tape OOPS

Hallo,

I use the 1.3.30 kernel with the ncr-patches at
ftp.pvv.unit.no /pub/Linux/ALPHA/ncr/
applied as the only patch.
I have gcc2.5.8 and libc-4.5.26 and Scsi-devices, either at the AHA1542CF or
at a NCR810 with the AHS-bios disabled.

Running both kernels gives a OOPS while accessing the tape with "tar tf
/dev/nrmt0":

Here(,I hope, )the relevant part from System.map:

001be96c t _st_write
001bf2ac t _st_read
001bf90c t _st_set_options
001bfa1c t _st_int_ioctl
001c04fc t _st_ioctl
