It is not necessary to install kmax to reproduce the issue. You can
choose either 1 or 2 to reproduce it. We will update the wording to make
this clearer.

If kmax installation failure is blocking method 1, could you please try
method 2 to see if the issue can be reproduced?

$ wget https://download.01.org/0day-ci/archive/20240217/202402171431.MzqHz3g2-lkp@intel.com/config -O .config
$ make ARCH=powerpc olddefconfig
