I just used Symantec Live Update to install the latest Norton utilities patch. After this, I started getting kernel panics. Fortuantely, these kernel panics did not occur right after reboot, but after the machine was up for about five minutes (I suspect Norton Filesaver is to blame). This "delayed" panic gave me time to disable journaling on my drive. I have received no more panics since I disabled journaling. You can read about the problem in Symantec's knowledge base article 2002120309434011.
[Editor's note: I know this has been covered on other Mac sites, but I thought it deserved a spot in the database here for those who might be searching in the future...]
