Interesting that we both get failures on Core i5 processors and
Debian-family operating systems. I am not using the Debian kernel (I
build a variant of the Guix kernel), but I do use the Debian package
tooling to manage it.

Could be, but the question is what? The build environment isolation
doesn't account for things like filesystem, kernel version, time of day
(👀), CPU bugs... besides the common culprit of some race conditions in
the test suite.

Are you using the same kernel versions on your two machines? I guess the
kernel configs likely don't match between them.
