I'm using a QuadG5 under Debian PPC right now, and indeed, it seems like I have a similar issue (i.e. it takes *forever* for the machine to halt). In my case it does end up powering itself off, but sometimes it even goes in a state where all the fan are running at top-speed. And indeed, I remember having some message in the console about CPUs "unplugging" themselves. > > I have one of these guys at work, I can give it a try next week. > Great. While you're at it, is there any chance you could try to get "server_mode" to work for this machine (or any SMU-based machine for that matter). You know, so that the machine reboots after a power failure :-) Thanks a lot Ben ! - Romain > Cheers, > Ben. > > > _______________________________________________ > Linuxppc-dev mailing list > Linuxppc-dev@lists.ozlabs.org > https://lists.ozlabs.org/listinfo/linuxppc-dev >
