init died during installing picobsd

[solomon]

hi there,
I have built picobsd for bridge. My system is freebsd 7.2. It is built
successfully and i burnt it to writable cdrom and try to install it to
my dell pc. It hangs up with "init died ..." message.
I run the alltrace command of the ddb and found the following message
...
...
Tracing comhi mand swapper pid 1 tid 100000 td 0xc4049000
kbd_enter_why(..........)...
panic(..........)......
exit1(.........)..........
kern_execve...........
execve.............
sysinit_add...........
fork_exit.............
fork_trampoline...........

Tracing command swapper pid 0 tid .............

where is my fault? if the information provided is enough to diagnose it.
thanx in advance
