I expect I will, Erik. I do tend to report progress as you have observed. I just woke up with another thought about the crashing. Something in that install, same install cd was used, is tickling the drive led at about 1.5 second intervals. The other, supposedly identical machine has never done that. And this crasher has already destroyed one hard drive.. Methinks I am going to log into it, and install htop, something tickling the drive that often ought to be right at the top of the cpu usage list. I'll post the result of that too.
