(Obviously you should be able to, but if you 'unload' the default kernel and load any other kernel, including /boot/kernel/kernel itself, you will run into the panic that you're seeing). This means that the only way to "test" a kernel is to install it as the real kernel, and hope it works. Note that if it does not work, you will have no way to load the previously-working kernel...\ (unless you set up a multi-boot situation) So, this is a rather risky thing to do. I'm pretty sure that all the changes that Peter had in that 'kernel.xorg' have now been committed to the base system. >Does xorg already work on powerpc? I know Peter was working on this. There was still some problem with it the last time I tried it, but I forget what the details were. I know it wasn't working for me, and Peter was going to check for the same problem on some powerbook or ibook that he had access to. >(BTW the usb Keyboard does not work inside DDB...) It won't work for the panic which happens when loading an alternate kernel, because the panic happens too soon. I don't know if it will work for panics which happen later in the startup process. >I tried to compile my own world/kernel, but gcc crashes during >compile. From reading the mailinglist archive I was under the >impression that I don't need to cross compile anything. You do not need to cross-compile anything. However, there are a few updates to parts of gcc which you do still need to add yourself, because they have not been added to the base system. Looks like they are updates to: http://people.freebsd.org/~grehan/rs6000.c.diff http://people.freebsd.org/~grehan/sysv4.h.diff -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
