Hi

I received a similar problem during booting into single user mode upon 
startup. I hope the following helps:

mounting root from ufs:/dev/ad2s1a
start_init: trying /sbin/init

VOP_STRATEGY on VCHR
:0xc189a00: tag none, type VCHR, usecount 5, write count 0, refcount  6, 
flags (VV_OBJBUF)

backtrace
spec_strategy
spec_getpages
ffs_getpages
vnode_pager_getpages
exec_map_first_page
kern_execve
execve
start_init
fork_exit
fork_trampoline

--- trap 0x1, eip = 0, esp = 0xcbaaed7c, ebp = 0 ---
