dbus is the problem. After booting up, 2-3 dbus processes are listed: 1-2 "dbus-daemon" and a "dbus-launch". Killing "dbus-launch" fixes the problem and makes one "dbus-daemon" disappear. > Do you get the problem if you ssh into the box from another box? What > about a serial console?

I don't know whether the hardware errors are related, but I'm beginning to not trust the PCDoctor software included on the ThinkPad Rescue & Recovery media. It doesn't include any more information than what is in this message (unless I'm missing something). Linux isn't complaining about any hardware and everything seems to work. > Do you have the problems with any other OS?
