FreeBSD used to have an irritating boot delay in 4.4. It was gone in
~4.6, never reappeared in -STABLE, but is there in -CURRENT.
(I've seen it also mentioned in some vmware documentation).
Applying this patch fixes it:

ata_prtdev(atadev, "%s identify failed\n",
command == ATA_C_ATAPI_IDENTIFY ? "ATAPI" : "ATA");
free(ata_parm, M_ATA);
I'm not familiar with the ata code, but I can't see from ata-all.c
which harm this could cause.
