Subject:   Accessing primary&secondary ide interface freezes 2.1.5

I just received a new 2 gig ide hard drive and promptly installed it in my
computer, attaching it to the secondary ide interface on my motherboard
(which is a cmd640b controller).

Anyhow, the drive is detected on bootup:

wdc0 at 0x1f0-0x1f7 irq 14 on isa
wdc0: unit 0 (wd0): <QUANTUM LIGHTNING 730A>
wd0: 696MB (1427328 sectors), 1416 cyls, 16 heads, 63 S/T, 512 B/S
wdc0: unit 1 (atapi): <CD-ROM CDU55E/1.0u>, removable, accel, dma, iordy
wdc1 at 0x170-0x177 irq 15 on isa
wdc1: unit 0 (wd2): <Maxtor 72004 AP>
wd2: 1916MB (3924144 sectors), 3893 cyls, 16 heads, 63 S/T, 512 B/S

And accessing the drive works fine.  I managed to fdisk it and disklabel
it for FreeBSD.

However, the problem comes when I try to access both interfaces (i.e. the
cdrom and the new 2gig hd, or my old 730meg hd and the new 2 gig hd) at
once, at which point the computer simply freezes completely.  Obviously
this makes this setup totally unusuable.

Has anyone seen this before??  Any way to avoid this?  Any suggestions
whatsoever?  I've been banging my head over this for weeks now.

Thanks,
