Re: [PATCH][RFC] sched: Isochronous class for unprivileged soft rtscheduling

Hi Con

I just played with your SCHED_ISO patch and found a simple way to crash
my machine.

I'm running this as unprivileged user with SCHED_ISO:

main ()
{
while(1) {
sched_yield();
}
}

The system hangs about 3s and then reboots itself.
2.6.11-rc1 + 2.6.11-rc1-iso-0501182249 on an UP Athlon XP.

With real SCHED_FIFO it just lockup the system.
