Here it says 5.3% regression instead of 16.1%.
The phrasing right above suggests it's a different test, but it's
confusing since there's nothing here in the table description (test
parameters) that differs from the test details above.
It's the same test but on a different machine IIUC.

Following the instructions from the 'reproduce' file, it fails to
install the job:

fdmanana 13:29:05 ~/git/hub/lkp-tests (master)>
Alternatively, tried to run reaim directly following the script from
https://download.01.org/0day-ci/archive/20250612/202506121329.9d1f4d50-lkp@intel.com/repro-script
The problem is I can't find debian packages for reaim, and going to
sourceforge to get the source, and the latest is
osdl-aim-7.0.1.13.tar.gz (from 2004!), it doesn't compile, there are
tons on warnings and errors.
Applying the patch from lkp at
lkp-tests/programs/reaim/pkg/reaim.patch doesn't help either.
