Hi all, I haven't been able to boot any kernels after linux 3.2 on my
SGI O2.  I've tried linux-3.3.5 and linux-3.4.0, but neither would boot.
Unfortunately I don't have further information such as a kernel panic,
since I don't get any video output after the kernel is loaded.  I've
attached my linux-3.4 .config.  Anybody know what patches I might need
to get the latest kernels booting on this system?

I have had problems as well.

Someone should configure a serial console and early printk to see if
they can see what is happening.

Could one of you bisect the bug?
