Hi,

I don't *have* anything on IRQ 20.
Here's the output of vmstat -i after >2 days uptime:

[root_at_ranger] ~# vmstat -i
interrupt                          total       rate
irq0: clk                       22888351         99
irq1: atkbd0                       20530          0
irq8: rtc                       29298041        128

irq15: ata1                           46          0
Total                           52845214        230
[root_at_ranger] ~# uptime
10:50PM  up 2 days, 15:36, 5 users, load averages: 0.14, 0.14, 0.11

Note that this is *without* the suggested loader.conf option.
