no /dev/disk/by-id... on boot

After last upgrade Arch won't start and write that there is no /dev/disk/by-id/ata-SAMSUNG_HD403LJ_S0NFJ1KP802892-part3 device.
When I try

echo /dev/disk/*

I see that there are no /dev/disk/by-id directory.

I use grub and in menu.lst i have (I didn't change this file after upgrade):

...
# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-id/ata-SAMSUNG_HD403LJ_S0NFJ1KP802892-part3 ro
initrd /kernel26.img

# (1) Arch Linux
title  Arch Linux Fallback
root   (hd0,0)
kernel /vmlinuz26 root=/dev/sda3 ro
initrd /kernel26-fallback.img
...

Arch Linux Fallback starts normal, and after boot i have /dev/disk/by-id/ata-SAMSUNG_HD403LJ_S0NFJ1KP802892-part3.

I tried to downgrade kernel, but it's not solves the problem (still no /dev/disk/by-id).

What can I do better than change grub configuration to always use /dev/sda3 instead of /dev/disk/by-id/ata-SAMSUNG_HD403LJ_S0NFJ1KP802892-part3 ??

PS. Where is log from boot time?

Re: no /dev/disk/by-id... on boot

Use uuid instead.

ls -l /dev/disk/by-uuid

Kernel boot stuff is in dmesg, remove first line in /etc/issue (you'd better backup it) to disable the screen cleaning of the first console.
