I was at the forums, and I noticed this thread http://forums.macrumors.com/showthread.php?t=56207 So, I had the same experience with a kernel panic, and I took the decision to start a new topic, requesting information and solution to my kernel panics with 10.3.8. http://forums.macrumors.com/showthread.php?t=113167 Others have been experiencing kernel panics, too! If you are unsure of what I am talking about, just read the two links above. And the most strange thing is that in most cases, systems were stable until 10.3.7, but kernel panics started to increase after the 10.3.8 update. Same thing happened to me. So, this topic is more like a poll, rather that a discussion. I would like you to report here whether your system has become more unstable after the 10.3.8 update or not. Have you too been experiencing kernel panics with 10.3.8?
