Friends,

I am trying to port Netbsd on IXP2400/xscale bord,
and i am going to mount ffs as a root file system

I have problem related to file system

1)  file sys/kern/init_main.c  fork1 function doesnot execute start_init =
process(user space process) ,=20

fork1( l, 0, SIGCHLD, NULL , 0, start_init, NULL, NULL, &initproc)

can anyone tell me how & when start_init process has been executed??

2) even in above file (sys/kern/init_main.c) kthread_create1 doesnt =
create kernel thread

 kthread_create1(uvm_pageout, NULL, NULL, "pagedeamon");
 kthread_create1(sched_sync, NULL, NULL, "ioflush");
 kthread_create1(uvm_aiodone_daemon, NULL, &uvm.aiodone_proc, =
"aiodoned");

can anyone tell me why it doesnt create kernel thread??

suprisly, I am not getting error or trap signal during executation..
