Are you running linux? If so, what version? It is a known problem that
in all but the very latest versions of the linux kernel, an older
version of the coda module was included which caused the problems you
described under certain circumstances (preventing you from rmmod-ding
the module).

I think this has changed in newer releases (I am using 2.2.13, it
works fine so far).

You can alternatively exchange the module, taking the original one
from the Coda www site instead. (Just compile and copy to
/lib/modules/.../coda.o).
