Those are code addresses, not the faulting virtual addresses.

Line 2895 in my pmap.c is:
int
pmap_ts_referenced(vm_page_t m)
{
register pv_entry_t pv, pvf, pvn;
pt_entry_t *pte; <<<< here
That's not code. :) Pop up gdb -k on your kernel.debug and do
'l *0xc02cbbab' and 'l *0xc02cfb9b' to get the exact line it
faulted at.

I don't think you need serial ddb yet.
