After the last crash the system compiled
editors/texworks without problems (uptime ca. 18 hours)
with superpages disabled:
root@quad:/usr/home/gwgpi # sysctl vm.pmap.
vm.pmap.sp_enabled: 0
vm.pmap.pv_entry_count: 10917
vm.pmap.pv_entry_max: 1744848

In the following I have done:
make -j10 buildworld in /usr/src
The system crashes after ca. 1 hour.
I tryed to get a coredump, but that did not work:
