>Description:
After several uneventuful usr-test runs on a Pi3B, the system panicked and rebooted.
The usr test suite was nearly complete; log portions follow below.
It looks like the last commands run were in the fs/ffs/t_snapshot case snapshotstress.

Automated Test Framework run command:
/usr/bin/atf-run | /usr/bin/tee /log/tests-${nm}-${dt}.log | /usr/bin/atf-report >/log/tests-${nm}-${dt}.txt 2>/log/tests-${nm}-${dt}.err

Unknown.
I will isolate this case and run it more frequently to see if/when the fault repeats.
At least 10 automated test runs finished without this problem occurring.
