Haven't tried it on amd64. The systems that show this problem here are
both notebooks with AMD processors running 32-bit:
FreeBSD sat.wonkity.com 9.0-CURRENT FreeBSD 9.0-CURRENT #0: Sun Sep 20 22:42:33 MDT 2009 root at sat.wonkity.com:/usr/obj/usr/src/sys/SAT i386
FreeBSD acer 8.0-RC1 FreeBSD 8.0-RC1 #0: Sun Sep 20 21:00:19 MDT 2009 root at acer:/usr/obj/usr/src/sys/ACER i386
The first is a Turion 64 X2 with 3G RAM, the second an Athlon 64 X2 with
4G.
Interestingly, a desktop system with an Intel E8400 had no problem with kldload atapicam:
FreeBSD lightning 8.0-RC1 FreeBSD 8.0-RC1 #0: Sun Sep 20 09:39:17 MDT 2009 root at lightning:/usr/obj/usr/src/sys/LIGHTNING i386
The only other system available is an Atom-based netbook with no CD
drive and BETA4. It also kldloads atapicam without a problem, but may
not be a useful test.
