Hola.

Adept-notifier show me a new kernel update, I thought it was for security or so...

i686 with 2.6.20-15 working, sda1 <-ntfs sda2 <-fat32 sdb1(swap), sdb2 , sdb3, sdb4(root) <-ext ALL IDE DEVICES, but called /dev/sdxy
After upgrading to 2.6.20-16, Grub menu entries about sda1(windowsXP), sdb2, sdb3, (Guadalinex, based on ubuntu) disaperar, but not about sdb4: 2.6.20-[12/15/16]: changed UUID
In Grub menu.lst:

(...)
title Ubuntu, kernel 2.6.20-16-generic (recovery mode)
root (hd1,3)
kernel /boot/vmlinuz-2.6.20-16-generic root=UUID=70b3941b-8bc6-47bf-96a0-68c6c7cab909 ro single
initrd /boot/initrd.img-2.6.20-16-generic

initrd /boot/initrd.img-2.6.20-15-generic
quiet
savedefault
(...)

In Grub menu.lst~:

(...)
title Ubuntu, kernel 2.6.20-15-generic (recovery mode)
root (hd1,3)
kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=41aa5966-7515-4be4-b056-a65f5ac9686c ro single
initrd /boot/initrd.img-2.6.20-15-generic

I mean, UUID changed.

Trying to start new 2.6.20-15 or 2.6.20-16:

"
Starting up...
Loading, please wait...
          Checkboot= rootarg cat /proc/cmdline
          or missing modules, devices: cat /proc/modules ls /dev
ALERT! /dev/disk/by-uuid/70b3941b-8bc6-47bf-96a0-68c6c7cab909 does not exist. Dr
opping to a shell!

BusyBox blah blah blah
(initramfs)
(...)
"

/dev/sdxy doesn't exist and /dev/hdxy appears for the first time on my kubuntu filesystem.

Recovered old entries in menu.lst, 2.6.20-15 works again, some multi-claimed inodes but fixed with fsck.

should i change UUID at Grub menu.lst 2.6.20-16 entrie?

Hopping being helpful, and sorry for my poor english.
