>Description:
NetBSD hangs very early in the boot process (before clearing the
screen) on a PowerBook 150. The included patch lets it at least clear
the screen and start printing boot messages, but it still hangs while
setting up the MMU. I think this is because get_pte() sets TT0 to
transparently translate the entire address space, moving the currently
executing code out from under the program counter. I haven't really
looked into it though...

>How-To-Repeat:
Try to boot NetBSD on a PB150.

>Fix:
This doesn't actually get NetBSD booting, but it's a start:
