Heh. I am using LinuxPPC 2k and the -stable tree from the rsync server. My symptoms include a wandering mouse pointer: i.e. when I am typing rapidly, X will occasionally think I've clicked the mouse button and the focus goes to where the pointer was located. I also have strange problems with my lombard locking up when I leave it in the screen saver overnight or turn the brightness all the way down. I haven't had any problems related to massive network activity. If I don't boot into MacOS enough to just get the initial grey screen and then reboot and let yaboot load, I get some really funky effects in X. Specifically, lines that should be vertical turn diagonal and stuff like that. As for the USB->serial adapter, I have one from Keyspan which several people are working on developing drivers for. Search the list archives for more detail on that. --- Mario Scarpa wrote: > Michael Schmitz wrote: > > > > > I am wondering if any of the developers who do > kernel > > > related work on LinuxPPC have any suggestions > for us > > > on how to deal with this.
