I'll bring this to vendor-sec now. Thanks. Yes, the fixed version is 1.4.1 (not 1.4 like I remembered) I noticed the problem about 2 months ago with my laptop, because after every suspend/resume (reloading the network driver) klogd ate 100% cpu. After searching if others had noticed the same symptoms I found that 1.4.1 has the bug fixed. The 1.4.1 version is available from: http://www.ibiblio.org/pub/Linux/system/daemons/ (I think the klogd cpu bug is mentioned in the changelog). -Jarno -- Jarno Huuskonen - System Administrator | Jarno.Huuskonen@private University of Kuopio - Computer Center | Work: +358 17 162822 PO BOX 1627, 70211 Kuopio, Finland | Mobile: +358 40 5388169
