Hi,
I'm missing some bits of the history here. With commit
23b4bd448a61a8934fb2354d2d0add3c20c0c392 I got this panic. I shared it with
Matt.

Unread portion of the kernel message buffer:
panic: bad *ptep 0000000000000000 sva ffffffe04b78e000 pte_pv NULL

Debugger("panic")
------
After that, Matt committed this one: a505393fd1a1920367affae433de8573462fe68c
I tried to do my test again and I finally got infinite messages saying:
swap_pager: indefinite wait buffer: offset xxx size 4096
The virtual machine was not responding anymore and I couldn't escape to DDB
either.
Cheers,
Antonio Huete
