Just so we know we are on the same track, I'm currently booting from the 
netbsd.GENERIC-6.tar.gz kernel from 19990628 which reports it's self as 
NetBSD 1.4D.

ps shows:

 0     -1    0   0  3  0x20204     swapper   scsipi_

and another trace shows:

_Debugger(140ee0,376a,1f5e50,353a,0) + 6
_nmihand(0,ffffffff,0,0,0) + 26
_mi_switch(2704,2200,0,8,0) + 12
_tsleep(4e0000,11,1255da,0) + 162
_scsipi_execute_xs(4e0000) + ac
_scsi_scsipi_cmd(4d9e00,1f5ef2,6,0,0) + 9c
_scsipi_prevent(4d9e00,1,180) + 44
_sdopen(401,0,6000,0) + e8
_sdsize(401,2704,ffff2200,1f3184,60000000) + 58
_cpu_dumpconf(0,0) + 46
_main(80040322,60000000,0,ffffcffc,280) + 380
_exec_aout_prep_zmagic() + 10a

Is there a minimum swap space that I'm not meeting or something? When I 
first did the system there was no swap space, but I completely wiped the 
HD and rebuilt it with the partitions I posted in the earlier message so 
there are separate U&R and Swap.
