Login Window Kernel Panic - Fast User Switching
I have the sam issue on both of my machines. This kernel panic occurs randomly when clicking user to login, but seems to happen more often when switching to another user while leaving the current user logged in. It also occurs more often on my Mac Pro... I wonder if it is affected by the lag time for the multiple drives needing to spin up by chance. The following is a portion of the crash logs that all looked basically the same.

Though this may not be directly related, a kernel panic occurred also by simply connecting my two currently logged in macs via firewire 800 to do file sharing.
That crash report had the back trace kernel extension related to firewire drives of course.
I have root user enabled on both machines.
