Hey guys. I've found a bug in modprobe where it generates bad strings and
makes sytem calls with them. The following patch seems to have fixed the
problem. It is rather inherited elsewhere, as there seems to be incorrect
entries in the list which results in more dependencies than really exist for
a given call to mod_process. But, this patch prevents the bad text from
going to the screen. You will notice there are cases where lcmd goes
unmodified before calling system.

Please consider the following patch.

Thanks.

-Steve
