illegal hardware instruction

[JuanPelota]

Hello,

I have made a USB disk with a persistent The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali).
I managed to boot on it on a forgotten computer at my job.
Unfortunately hashcat don’t run on it.
It doesn’t initialize the backend and says : illegal hardware instruction.

I am not a tech guy. Is it possible that a CPU/computer is restrained through some kind of hardware setting ?

Thanks
