I'm seeing the same thing on my P630. After seeing all of the great
progress which is being made on the Quadras, I thought I'd try
netbsd.quadra only to have it die in exactly the same way John
describes. With earlier kernels and the recent ADB changes which give
me a working keyboard, I was able to at least get into debug
mode. Anybody have a solution yet?
