Description

While investigating this bug https://dev.haiku-os.org/ticket/14802 on real hardware, i have tried to reduce the number of active CPUs to reproduce the problem using ProcessController's Deskbar menu. And sometime, it freeze the system. This could happen on 64 bits but also on 32 bits version of Haiku.

Not critical for a normal use, but users will probably play with this option anyway.

Did you disable all CPUs? We don't allow this in Pulse but I'm not sure if we added the check to ProcessController as well.

No, the goal was to keep only one active CPU to reproduce the test case
