chkrootkit has an impedance mismatch with ps. This has been discussed
before.

antalya:~# chkrootkit -x lkm
ROOTDIR is `/'

PID     3: not in ps output
CWD     3: /
EXE     3: /
PID     4: not in ps output
CWD     4: /
EXE     4: /
PID     5: not in ps output
CWD     5: /

PID     6: not in ps output

You have     4 process hidden for ps command

ps -ef lists these:

root         0     1  0 Jan19 ?        00:00:00 [ksoftirqd_CPU0]
root         0     1  0 Jan19 ?        00:03:40 [kswapd]
root         0     1  0 Jan19 ?        00:00:00 [bdflush]
root         0     1  0 Jan19 ?        00:00:06 [kupdated]

So ps does not give chkrootkit a PID, but /proc has those processes.
