There is a dump of the pg->mdpage.pvh_attrs values before crash

pg: 0x81123c34 attrs: 0
pg: 0x811237c0 attrs: 1000
pg: 0x81123b9c attrs: 0
pg: 0x81123a6c attrs: 0
pg: 0x81123560 attrs: 1000
pg: 0x8112380c attrs: 0
pg: 0x81124484 attrs: 83
pg: 0x81124010 attrs: 1083
pg: 0x81124010 attrs: 82e28163
panic: kernel diagnostic assertion "(pg->mdpage.pvh_attrs &
PVF_KENTRY) == 0" failed: file

As you can see the value for those attributes looks like garbage. Is
this mean some bug in the cache addressing algorithm?
