We just upgraded from base SLES 8 (kernel 2.4.19-3) to SP3.
We noted is the tape module configuration change. We hand-
wrote a sysinit script to modprobe tape390, and now an
implicit insmod for tape_3590 fails. Sure enough, the new
modules.dep lists two modules: tape_3590 and tape_3590_mod
with the "main" tape driver (kernel/drivers/s390/char/tape390.o)
as the sole dependency for each.

True to form, lsmod shows nothing so named as loaded, and an
attempt to attach a 3590 fails to register the device. No I/Os
issued against /dev/ntibm0 work when we attach a 3590, but all
I/Os (and the contents of /proc/tapedevices) work for 3490
devices.

When I try to cd into the directory with tape_3590.o and tape_
3590_mod.o in it and issue insmod against either or both, I
get flooded with "unrecognized symbol" messages ... I guess
these don't match the kernel.

The new initrd doesn't have/load any modules that would affect
the tape* chain.

Any ideas where I might be bumping my head? Fix?

TIA,
