I checked the kernel logs looking for this error message. The system was upgraded to Etch on April 10, and there are NO entries of the NWFPE log until after the DSA-1286-1 security update is installed. So it looks like this might be related to the changes introduced with this update.
Going through the System.map file, it appears that the exception occurs in the "PerformFIX" routine. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
