Ultra 10

Uwe is having issues with booting Debian GNU/Linux on a Sun Ultra10.

Uwe, if your box has a Creator3D card, it might be that the Linux framebuffer is, by default, sending its output there. If you have no monitor, it stops when the screen turns black.

There's a kernel boot option to switch the default framebuffer from the Creator3D to the ATI something-64 (can't remember the name; the atyfb framebuffer is what drives it), so that you'll see something again; apart from that, it should work.

Interestingly, the 2.4 kernel works differently; if you boot with linux-2.4 instead of linux, you'll get a working installation.
