Good day,
I've installed (several times) on a ThinkPad T-40, trying both manual kernel
config and genkernel. I followed the online manual explicitly (I think). The
machine is currently loaded with the manual config. Either way, the results
are similar.
Grub shows the two boot options, then begins loading the OS.
The machine begins to boot, starts loading modules, then kernel panics:
VFS:Cannot open root device "hda3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
There is a single fixed disk:
Device Boot Size System Filesystem Mount
point
======= ==== ===== ========= ========= =========
/dev/hda1 * 32M Linux ext2
/boot
/dev/hda2 3G Linux swap none none
/dev/hda3 ~71G Linux ext3 /
I am able to mount and use these partitions after booting from CD.
/etc/fstab (/mnt/gentoo/etc/fstab when booted from disk) looks good.
Filesystems ext2 and ext3 are compiled into the kernel.
Grub details:
device.map
(hd0) /dev/hda
grub.conf
default 0
timeout 5
splashimage=(hd0,0)/boot/grub/spash.xpm.gz
title=Gentoo Linux 2.6.17-r8
root (hd0,0)
kernel /boot/kernel-2.6.17-gentoo-r8 root=/dev/hda3
title=Gentoo Linux 2.6.17-r8 (rescue)
root(hd0,0)
kernel /boot/kernel-2.6.17-gentoo-r8 root=/dev/hda3 init=/bin/bb
I used grub-install /dev/hda with no errors. I've played around with the
"root=" entry, but to no avail - not sure I'm understanding this one...
The kernel image appears to be valid, with no typos in filename/grub
entries.
Any ideas? Seems that the kernel begins to load, but can't mount the root
filesystem?
Thank-you for any pointers.

You're on the wrong list. This list is for development discussion for the GLI
project. Ask on the gentoo-user list.

Andrew is right, this is wrong list. Anyway, you should check that
modules for your IDE controller are loaded in initrd (or compiled into
kernel).
You can do this by selecting the second choice in grub (rescue). It
will boot into busybox (a very basic shell) and you should be (un)able
to mount filesystems. I don't know what exactly will busybox do for
your, but maybe you will need to create device node by hand.
For more informations, please write to gentoo-user list, or contact me
personally (but NOT this list, unless this is gentoo-installer's
problem).

All: thank-you for the help so far. I have posted this on gentoo-user as
well, and will continue to work with folks individually here or publically
on that list.
The responses so far have helped - Bigfish (Richard), I may respond directly
to your RFI as you may be able to pinpoint the driver(s) I'm missing. I have
added driver support in newly compiled kernels and gotten different errors -
but I think I'm close.
Again all - thanks. I'll pursue on gentoo-user...

There are also about 1000 posts about this on the forums and on the
"installing Gentoo" forum there is a specific thread on Grub errors and
how to deal with each one.
