Details : OpenBSD 4.7-current (GENERIC.MP) #482: Sat Apr 3

>Description:
After discovering that the my root disk no longer shows up with the
bsd.rd for the latest snapshot, I tracked down the problem to revision
1.80 of sys/dev/ata/atascsi.c.
With kernel source checked out on 2010-04-19 10:50 UTC, all three of
my AHCI disks are detected correctly:

However when I update to five minutes later:
$ sudo opencvs -q up -D '2010-04-19 10:55 UTC' -dP
Password:
U dev/ata/atascsi.c
U dev/ata/atascsi.h
$
The first two disks disappear:
