Log when an interrupt handler takes more than 3ms to complete. This doesn't appear to add much overhead, and could help narrow down future packet loss problems. At the moment, on our platform, the only IRQ that seems to have this problem is SATA. Probably someone should try to fix that, sometime, because there's no obvious reason the SATA IRQ would need to spend milliseconds with interrupts disabled.
