>Description:
	
Booting 2-floppy laptop install set uvm_faults.
Booting 3-floppy laptop install set (with symbols) also uvm_faults, but
more informatively. 10-finger copy follows.

When booting, a warning is displayed early on "memory map overlaps with
``compatibility holes''"

Eventually, it goes to:

uvm_fault(0xc04c8ae0, 0x0, 0, 1) -> e
kernel: page fault trap, code=0
Stopped in pid 0 (swapper) at   rbus_new_root_share+0x9:  cmpl 0
xc(%ecx),%edx

I have the rest, but didn't want to type it all. If something specific would be useful, ask.
