The problem is not in your /etc/fstab it's in /boot/grub/grub.conf
root=/dev/something is not right.
I don't know anything about SATA but post your grub.conf and someone else might be able to help you.

I'm assuming you're running kernel 2.6.x? I've seen this problem ALL OVER the place -- not just with Gentoo. I've had the same problem with my config using both GRUB and LILO, so who knows.
At this point, I've recompiled the kernel 4-5 times with no joy yet. Frustrating!

Since I think everyone can benefit from this exercise, here's my current (non-working) config.
/etc/fstab:
| Code: |
/dev/sda2 / ext3 noatime 0 1
/dev/sda1 /boot ext3 noauto,noatime 1 2
/dev/sda6 /usr ext3 noatime 0 2
/dev/sda3 /var ext3 noatime 0 2
/dev/sdb1 none swap sw 0 0
/dev/sda5 /opt ext3 noatime 0 2
/dev/sda7 /staff ext3 noatime 0 2
/dev/sdb2 /home ext3 noatime 0 2
#/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0
|
/boot/grub/grub.conf:
| Code: |
# Which listing to boot as default. 0 is the first, 1 the second etc.
default 0
# How many seconds to wait before the default listing is booted.
timeout 30
# Nice, fat splash-image to spice things up :)
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.3-r1
# Partition where the kernel image (or operating system) is located
root (hd0,0)
kernel (hd0,0)/vmlinuz root=/dev/sda2
|
/boot/grub/device.map:
| Code: |
(hd0) /dev/sda
(hd1) /dev/sdb
|
Mounts after chrooting off of a Knoppix boot:
| Code: |
/dev/sda2 on / type ext3 (rw)
/dev/sda1 on /boot type ext3 (rw)
/dev/sda3 on /var type ext3 (rw)
/dev/sda5 on /opt type ext3 (rw)
/dev/sda6 on /usr type ext3 (rw)
/dev/sda7 on /staff type ext3 (rw)
/dev/sdb2 on /home type ext3 (rw)
none on /proc type proc (rw)
|
<-- stumped.
I'm going to compile in every SCSI driver, just for the hell of it.
lsmod on the Knoppix boot only shows the aic7xxx.o driver loaded for scsi (which is correct):
| Code: |
Module Size Used by Not tainted
ext3 64164 7 (autoclean)
jbd 46356 7 (autoclean) [ext3]
autofs4 8756 1 (autoclean)
af_packet 13512 0 (autoclean)
nls_iso8859-1 2876 0 (autoclean)
ntfs 50944 0 (autoclean)
msdos 4652 0 (autoclean)
eepro100 19380 1
mii 2256 0 [eepro100]
serial 51972 0 (autoclean)
usb-ohci 18184 0 (unused)
usbcore 57824 1 [usb-ohci]
apm 9768 0
rtc 6972 0 (autoclean)
cloop 8740 2
aic7xxx 132172 8
|
All of those modules are compiled into the kernel I'm using.
BOGUS!

After WAY TOO MANY recompiles, I have finally found the answer.
I missed a damn driver required to support my onboard scsi. 
The board I'm using, a ServerWorks GC-LE based board, has an Adaptec AIC7xxx onboard. Unfortunately, it also uses the Adaptec I2C driver, which I had *not* been compiling in (for hot-swap of drives.)
Compiled in, now using 2.4.25_pre7-gentoo-r2 -- going to re-try 2.6.3-gentoo-r1 and see if that works as well. At least I'm not retarded.

| I missed compiling this into my kernel as well. Thanks for the post. |
