This was rather general, not F14, question, how from messages line:

kernel: Pid: 2454, comm: ip Tainted: G        W 2.6.35.4-28.fc14.i686.PAE

possible determine, why is kernel tainted and which modul caused it.

Differences betveen 2.6.34 (F13 stable) and 2.6.35 (F14 soon) probably 
isn't too big (controll groups are only one notable thing). And, of 
course, I'm too lazy to register at development/testers ML for this one 
question only. Rather will wait for F14 release... Or LKML...
