hmm...   ^^^^^^^^
I don't understand... ;-<

you Sheevaplug happen software-interrupt-exception at 0x8008.  netbsd's
entry point is 0x8000.

Can you try ?

    # arm--netbsdelf-objdump -d your-SHEVAPLUG/netbsd

    c0008000 <marvell_start>:
    c0008000:       ee104f10        mrc     15, 0, r4, cr0, cr0, {0}
    c0008004:       e3c4400f        bic     r4, r4, #15     ; 0xf
    c0008008:       e28f50c4        add     r5, pc, #196    ; 0xc4
    c000800c:       e28f60c8        add     r6, pc, #200    ; 0xc8

Do you try to boot my test kernel?
# I replaced cpufunc_asm_sheeva.S to FreeBSD's.
# I see message "/etc/rc.conf is " from /etc/rc.  And, it hung up.  ;-)

Thanks,
