Under VA pressure (or kernel memory, or whatever) execing new processes will
panic the kernel (pmap assertion: pg != NULL, details to be filled in).

This happens for me when extracting set files (especially the huge debug
ones) to wd0 and login in via ssh, or see below.


Make sure you have plenty of space in /tmp (i.e. no tmpfs)
ssh into the box, then:
cd /usr/tests/fs/cd9660
atf-run | atf-report

Now wait like 10 minutes, then try to log in on the console
