>Description:
devfs does not handle IDE drives hanging off the second IDE controller
(wdc1) properly. Instead of trying to attach them as [r]wd2 and [r]wd3,
it tries to attach them as [r]wd0 and [r]wd1. Here is the evidence:

wdc0 at 0x1f0-0x1f7 irq 14 on isa
wdc0: unit 0 (wd0): <QUANTUM SIROCCO1700A>
wd0: 1628MB (3335472 sectors), 3309 cyls, 16 heads, 63 S/T, 512 B/S
wdc0: unit 1 (wd1): <WDC AC33100H>
wd1: 3020MB (6185088 sectors), 6136 cyls, 16 heads, 63 S/T, 512 B/S
wdc1 at 0x170-0x177 irq 15 on isa
wdc1: unit 0 (wd2): <QUANTUM BIGFOOT_CY6480A>
wd2: 6204MB (12706470 sectors), 13446 cyls, 15 heads, 63 S/T, 512 B/S
Device wd0: name slot allocation failed (Errno=17)
Device rwd0: name slot allocation failed (Errno=17)

(17 is EEXIST). 

>How-To-Repeat:
put 3 or 4 drives in a machine. Boot!
>Fix:
I would fix it if I had time. It should be a five-minute fix for the
author of devfs!
