This is after having upgraded to and booted into (long output line manually split for readability): # uname -apKU FreeBSD CA72_16Gp_ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT #65 main-n259064-f83db6441a2f-dirty: Sun Nov 6 17:08:00 PST 2022 = root@CA72_16Gp_ZFS:/usr/obj/BUILDs/main-CA72-nodbg-clang/usr/main-src/arm6= 4.aarch64/sys/GENERIC-NODBG-CA72 arm64 aarch64 1400073 1400073 I then started doing more builds and got the failure indicated later. /var/log/messages and dmesg -a output show no messages about the failure and no messages near the time of the failure. Unfortunately, the error did not reproduce via either: A) The reproducer materials in /tmp/ . or: B) Restarting the build that failed. Nor was a core file left behind to look at. The system has been stable for a long time prior to this (hours, days, weeks, months, . . .). The only new environmental thing has been I've starting using dpni0 (via the new DPAA2 support) instead of using an Ethernet dongle. This does not have a long history yet but I had been using it since after my prior FreeBSD update as well. It was a -j16 buildworld that got the failure. The failure messages look like: . . .
