chkrootkit found lkm trojan ?

[Micha Feigin <michf@post.tau.ac.il>]

I got the following output from chkrootkit but couldn't find any
explenation on what processes don't appear:

Checking `lkm'... You have     4 process hidden for ps command
Warning: Possible LKM Trojan installed

How do I check this?

I also got:

nothing deleted

I have reiserfs and had quite a few crashes lately due to some problem
with my instellation. Any ideas?
