xfstests generic/029, generic/030 and generic/031 now break with
current Ubuntu (26.04) due to a change in capitalization of hexdumps
in some tooling. See below. Has anyone found a way to workaround
this?

Again this is not coreutils, but the broken rust version.

I haven't hit this issue myself. These specific cases all rely on a _hexdump
helper, which actually executes the od command (od -Ax -t x1z) .
Therefore, you might want to check your coreutils package to see its version
and what changes have been made to od.
From what I recall, Ubuntu has been promoting the use of Rust-written uutils/coreutils
to replace the traditional C-based coreutils. It’s highly worth checking out, as
this could very well be the root cause of the issue you're facing :)
Thanks,
Zorro
