I saw such back on such old versions as well. For example:

https://lists.freebsd.org/pipermail/freebsd-hackers/2017-December/051942.html

is is report for the RPi2B V1.1 . -r326726 showed the "bad pte2"
problem. But your example does not involve exec_elf32_imgact .
(My examples might not have run into all cases of failure.)

head -r327485 has not done such for me. Also, by then head
had a fix for a boot-sometimes-hangs issue introduced in
-r326347 . (There still can be hangups when plugging in USB
drives after booting, at least on Pine64+ 2GBs.)
