I was looking at the implementation in sage/matrix/matrix0.pyx. There is
actually no test demonstrati
I have created https://trac.sagemath.org/ticket/25486 for this.

Hi Travis,
first of all: Thank you for figuring out the problem.

I have figured out what was going wrong: after #17272, the *generic*
algorithm was being called rather than the specific implementation, which
was still called _echelon_in_place_classical. I have added a
_echelon_in_place to the meataxe matrices to simply call this. We probably
should have desi

Travis said it might be #17272. Anyway, I am at it, and hope to fix the
problem in the next few days.
Best regards,

Dear Simon,
The patchbot I run (quasar) installs all optional packages whenever they
do work. It is a pain to maintain as at each beta release there is a
need to disable some of them and I sometimes provide fixes.
The wording might be misleading, but this is how optional packages are
