Bastien, Ben, Chris, Rogério, Will, Michel, Thanks heaps for your collective help! I was able to circumvent the regular bootup code and login (using the init/bin/sh parameter in the yaboot boot prompt). I could then manually mount my disks, hunt down the script running pmud and turn it off. Then I could re-boot normally and use dpkg to remove pmud-utils. My sense of helplessness has been overcome.
After I removed pmud-utils, I noticed that the /usr/sbin/pmud was still around (it came in it's own package) so in the interest of Science, I tried it. Yikes - I got a repeat of the problem I was having earlier. So pmud is definitely a bad idea to run on a new G4 desktop. (Well, *my* desktop, anyway. Maybe my hardware is particularly delicate, but i have no reason to believe so.) I quickly removed pmud as well. Thanks again folks! -- Bill -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
