I just ran into this with a kernel w/o NEWPMAP on a different PowerPC
system.  It looks like this is coming from softdep_pageiodone() when
it calls uvm_pageratop().  You will not see this panic if SOFTDEP is
disabled.  I don't know enough about UVM or SOFTDEP to know what might
be happening here.

In my case, the panic was preceded by some adw0 DMA errors, so I wasn't
sure if I had run into a disk error (I never saw these errors before
enabling softdep yesterday, though).

I didn't see this panic with NEWPMAP, but I did see a different panic
that was related to NEWPMAP.
