Norbert, you do not have the same file that I have.

You have:

grep FBSDID /usr/src/sys/dev/ata/atapi-cam.c
__FBSDID("$FreeBSD: src/sys/dev/ata/atapi-cam.c,v 1.42.2.4 2007/05/03
09:38:54 thomas Exp $");

I have:

grep -i FBSDID /usr/src/sys/dev/ata/atapi-cam.c
__FBSDID("$FreeBSD: src/sys/dev/ata/atapi-cam.c,v 1.42.2.5 2007/05/15
16:19:42 thomas Exp $");

If you don't wish to have the issue I have, I think it might be wise
to refrain from updating your source tree.
