SATA SCSI Id assignments - two drives being assigned the same Channel/Id/Lun on boot

In the thread "mount doesn't mount on boot-up" we have found a
problem with the way my SATA drives are being ID'd, as seen below.
# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: ST3160023AS Rev: 3.05
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi1 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: ST3300622AS Rev: 3.AA
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi1 Channel: 00 Id: 01 Lun: 00
Vendor: ATA Model: WDC WD5000YS-01M Rev: 07.0
Type: Direct-Access ANSI SCSI revision: 05
The first two entries appear to have the same Channel/Id/Lun -
the problem I'm having has to do with my third drive not being mounted
at boot. My fstab looks like this:
LABEL=/ / ext3 defaults 1 1
LABEL=/boot1 /boot ext2 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
LABEL=/home /home ext3 defaults 1 2
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
LABEL=SWAP-sda2 swap swap defaults 0 0
/dev/sdc1 /home/cj/archive ext3 defaults 1 2
This results in this error in my system log while booting:
Nov 2 00:37:04 localhost kernel: audit(1162445820.853:6): avc: denied { mounton } for pid=2338 comm="mount" name="archive" dev=sdb1 ino=65175554 scontext=system_u:system_r:mount_t:s0 tcontext=user_u:object_r:user_home_t:s0 tclass=dir
Nov 2 00:37:04 localhost kernel: audit(1162445820.853:7): avc: denied { mounton } for pid=2338 comm="mount" name="archive" dev=sdb1 ino=65175554 scontext=system_u:system_r:mount_t:s0 tcontext=user_u:object_r:user_home_t:s0 tclass=dir
The last line in my fstab relating to sdc1 is the issue - when I boot,
the process is trying to mount sdb1 instead, for a second time, since
that drive is already mounted by the 5th line in my fstab which starts with
LABEL=/home
Has anyone else encountered this? Guess I'm going to head over
to bugzilla and see if there are any reports of this, but, I'm wondering
if there's something I could have misconfigured that's causing this.
