Sorry if this has been discussed before; I didn't pay attention since
I thought the problem only was annoying messages.
This happens about a minute or two after I load atapicd, irrespective
whether I load it from loader.conf or the command line. This is on
VMware Fusion 2.
I'll try with GENERIC now.
