>Description:
One of the ATF test programs fails on 3 of 7 cases, only on a Raspberry Pi Zero 2W (GENERIC evbarm kernel). The same program fully succeeds every case, on other architectures including GENERIC64 evbarm / aarch64 / Pi 4.

Pi02W program executed:
$ file /usr/tests/lib/libc/c063/t_utimensat
/usr/tests/lib/libc/c063/t_utimensat: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /usr/libexec/ld.elf_so, for NetBSD 10.0, compiled for: earmv7hf, not stripped

(same program on GENERIC64)
$ file /usr/tests/lib/libc/c063/t_utimensat
/usr/tests/lib/libc/c063/t_utimensat: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /usr/libexec/ld.elf_so, for NetBSD 10.0, not stripped


Failures:
utimensat_fd
utimensat_fdcwd
utimensat_fdlink

The failing systems run on microSD media, while other systems are on SSD or USB storage.


>How-To-Repeat:
Two test results follow:

$  atf-run lib/libc/c063/t_utimensat

>Fix:
I have been unable to glean any root cause, nor why these specific 3 cases fail. I assume there is a common denominator.
