>Description:
When trying to build the system using build.sh, I got this after a few hours of compiling:

pmap_enter: freeing unused page 30c24000
Mar 29 21:48:51 galadriel /netbsd: pmap_enter: freeing unused page 30c24000
pmap_page_protect: pseg empty!
kdb breakpoint at 1335d58
Stopped in pid 6569.1 (sh) at   netbsd:cpu_Debugger+0x4:        nop
db> 

Is there anything I can do at this point to get more information why this happened?

>How-To-Repeat:
Out of three tries, this happened twice.  The machine in question is a Sun Ultra 1, running NetBSD 2.0 from the builtin SCSI HD.
