Your series of soft updates panic's was recently pointed out to me.
In looking at the traceback, I see things that look like this:
#80 0xc0164001 in boot (howto=256) at ../../kern/kern_shutdown.c:203
#81 0xc0164440 in at_shutdown (
function=0xc02b0f42 <__set_sysctl__debug_sym_sysctl___debug_rush_requests+2
882>, arg=0xc9bbb0c0, queue=0) at ../../kern/kern_shutdown.c:446
#82 0xc02226f2 in softdep_fsync (vp=0xc9bbb0c0)

tf_isp = -911024156, tf_ebx = 134664136, tf_edx = 29, tf_ecx = 29,
tf_eax = 95, tf_trapno = 7, tf_err = 2, tf_eip = 671803168, tf_cs = 31,
tf_eflags = 582, tf_esp = -1077945832, tf_ss = 39})

If you still have any of your crash dumps, it would be useful if
you could go into the first frame that has softdep_fsync in it (#82
above) and print out the contents of the inodedep:
print inodedep
print *inodedep
That should give me an initial clue as to what caused the panic.
