I use preemption all the time on all of my machines, which are *all* |
| 18 |
multi-processor or multi-core. The kernel preemption works just fine on |

all of them. What tends to be the problem is shoddy APIC or ACPI |
| 20 |
implementations on the cheaper (read, not server/workstation class) |
| 21 |
motherboards. |
