Filesystem errors on armv7 -current

A Pi2B running
FreeBSD pelorus.zefox.org 16.0-CURRENT FreeBSD 16.0-CURRENT #76 main-n289925-6c305c3c3129: Sun Oct 11 15:20:02 PDT 2026     bob@pelorus.zefox.org:/usr/obj/usr/src/arm.armv7/sys/GENERIC arm armv7 1600027 1600028

is reporting errors during installworld of the form

/usr: inode 67896768: check-hash failed

and

UFS /dev/da0s2d (/usr) cylinder checkhash failed: cg 846, cgp: 0xce917fd != bp: 0x4e2a15c5

There's an old bug report, 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267654

which looks somewhat similar but is marked "Closed FIXED".

So far, the errors have not resulted in any build or install stoppages,
but the install and reboot haven't completed yet.

Is it worth reporting this behavior as a new bug? Old bug? Other? Not?
It's true that the kernel lags world by one index digit. Not sure how
that happened.

I can post console output, but it's mostly repetitive, as if the
errors correct eventually or are ignored.

so below the warning limit
