Re: page fault on 1.2.0-RELEASE

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:vm_page_startup:
:	first_page 0x1
:	page_range 11
:	npages -2046298669
:	end -27020983583899648
:	new_end -27020983583903744
:	vm_page_array 0xc081a000
:	mapped 0xc081b000

    Something is seriously broken here.  Try making them
    separate printfs.  Also print out the 'total' variable,
    vm_page_buckets, vm_page_hash_mask.

:vm_page_startup 2:
:	phys_avail[i] 4096
:	phys_avail[i+1] 651264
:	last_pa 651264

:After the first call to vm_add_new_page, I see the panic below which I

:vm_add_new_page:
:	m 0xc081a000
:	m->queue 52410
:	vpq 0xc052ff88
:	flipflop 189185
:	vpq->pl 0xc052ff88

    Ok, we still have this issue of m->queue being too large.  Print
    out pa (%08llx), PQ_L2_MASK, PQ_FREE, and m->pc.

    I'm beginning to see an issue.
