Here's what I've learned since my initial message: 1. Other people have seen this problem (or something similar) as far back as 5.x. 1a. I noticed in my kernel config file that I did NOT have kdbmux in my 6.2 kernel config file, but I do have it in my 7.0 kernel config file. However, I also tried recompiling 7.0 without kbdmux, and the problem still occurs. 2. The problem only happens when I have xbattbar running. Whether or not I'm actually running on battery makes no difference. 3. Ssh sessions into the box do not appear to be affected. 4. If I plug in a USB keyboard, it does not seem to be affected. (Either with or without kbdmux.) I've added some KTR debugging statements to try to help me track this down, but I have not yet made much progress. Mike "Silby" Silbersack
