After installing to USB HDD, boot dies on kernel panic

Hi,
I'm trying to install Archlinux to external USB HDD (some WD disk, 320GB).
I create mountpoints (sdb1 - /boot, sdb5 - /, sdb6 /home, sdb7 - swap), everything ext4 (with ext3 I'm getting same results).
After selecting and installing packages I successfully exited installation.

Then I edit /etc/mkinitcpio.conf - adding usb, ide. Run mkinitcpio -k 2.6.30-ARCH -c /etc/mkinitcpio.conf -g /boot/kernel26.img. Everything is OK.
I edit /mnt/boot/grub/menu.lst to something like this:

root (hd0,0)
kernel /boot/vmlinuz26 root=/dev/sda1 ro vga=773
initrd /boot/kernel26.img

(Yes, sda1 because while booting is sdb fixed IDE disk).

Then I reboot, start booting. And it exits on kernel panic
Anybody knows, what to do? Fedora was OK on same disk....

Hmmm, OK.
I changed fstab and menu.lst, everything to sdb. It's still dying, but with different errors.

Some output (I need rewrite it to paper and then to computer :-/ ):

Waiting 0s before mounting root device
EXT4-fs: barriers enabled
kjournald2 starting: pid 702, dev sdb1:8, commit interval 5 seconds

kinit: Mounted root (ext4 filesystem) readonly
kinit: init not found
kernel panic - not syncing: Attempted to kill init
..some hex addresses and stack trace..

Could be a multitude of stuff. I reckon you ought to create a new mkinitcpio using the fallback kernel. This has sorted out most of my disk experiments

Re: After installing to USB HDD, boot dies on kernel panic

I think I have the same issue. Don't mean to hijack but there's probably no need to start a new thread. Kernel panic. Arch installed on /dev/sdb5 with /dev/sda (SATA) coming up as the first disk. Grub says (hd1,4) and is using UUID. Might I need to do the same thing, mkinitcpio ?
