I'm really sorry for following up to myself again, but the following
might be useful:
(gdb)
#8 0xc01bce28 in enroll (description=0xc02e3718 "vnode interlock",
lock_class=0xc0300fc0)
at /home/ryanb/FREDRIK_DP_INV/sys/kern/subr_witness.c:985
985 if (w->w_name == description || (w->w_refcount > 0 &&
Current language: auto; currently c
(gdb) p *w
$16 = {w_name = 0xc16fd8fe <Address 0xc16fd8fe out of bounds>,
w_class = 0xc0300fc0, w_list = {stqe_next = 0xc032fa50}, w_typelist = {
stqe_next = 0xc032fa50}, w_children = 0x0, w_file = 0x0, w_line = 0,
w_level = 0, w_refcount = 2, w_Giant_squawked = 0 '\0',
w_other_squawked = 0 '\0', w_same_squawked = 0 '\0'}
This is the instruction where the page fault occurred. As to how w_name
was clobbered, I have no idea.
