several times I've got the following problem (Linux 2.1.50, modutils-2.1.42):

After this error lsmod returns an empty list plus an error message. Obviously
the kerneld is in the story, too.
Unfortunately I haven't found a reproducable way to get this crash. If
you have new information or a patch or if you need more information about
my environment, please send me a note.
Thanx very much
