To be honest, you need to bisect. For reference, see
Documentation/admin-guide/bug-bisect.rst in the kernel sources.
Since you have problem with your old machine, you may want to compile
the kernel (which is a prerequisite for bisection) on faster machine,
then transfer the kernel image + modules into your old machine to
be installed there. Without bisection, no one will look into this
regression.

Thanks.
