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
irq9: acpi0 3902 0
irq11: cbb0 cbb1+++ 203530 0
irq12: psm0 117066 0
irq13: npx0 1 0
irq14: ata0 313747 1
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.
