So far the reboot hang hasn't repeated in half a dozen or so attempts.....
not sure if that's good or bad.

In the meantime the system ran stress2 (old version) for 12 hours 49 minutes,
the previous record was around ten hours. Interestingly, the crash did _not_ 
report "translation fault (L2)", but rather
"panic: pmap_growkernel: no memory to grow kernel". 

That's different, at least. 

Thanks for reading,
