Problem!! with boot and UUID

Hello!!:D
The last night I just full upgrade system pacman -Syu, kernel 2.6.27 to 2.6.28-3, but today Arch not boot, the error:
Atempting to create root device /dev/disk/by-uuid .............

Root device '/dev/sda6' doesn't exist, attempting to create it
ERROR Failed to parse block device name for /dev/sda6
ERROR unable to create/detect root device /dev/sda6
Dropping to a recovery shell.... type 'exit' to reboot
NOTE: klibc contains no 'ls' binary use echo * instead

If the device '/dev/disk/by-uuid .............' gets created while you are here, try adding 'rootdelay=8' or higher to the kernel command line
ramfs$_

Or something like these, don't remember very well,  tried the rootdelay=8 and the problem persist

Menu.lst from Grub and fstab have the same UUID
GRUB root=/dev/disk/by-uuid/e9d98cf9-015f-4513-ae84-eba302f18266
and fstab UUID=e9d98cf9-015f-4513-ae84-eba302f18266

Then I check the directory /dev/ and surprise!! anything here except for null, console

Any ideas?

PD: Sorry for my bad english, i learning it!

Re: Problem!! with boot and UUID

at a guess, i bet your initcpio didn't get rebuilt properly.  do you have /boot on a separate partition?  is it usually mounted?  if so, is it normally mounted ro or rw?

if you can boot your system--or chroot into it from a livedisk--try rebuilding you initcpio, making sure that /boot mounted and mounted rw.

Re: Problem!! with boot and UUID

I had a similar problem in my VirtualBox ArchLinux installation when I changed the virtual hard drive from
a IDE to SATA. Arch refused to boot with the same kind of error. I then reverted to IDE and modified
/etc/fstab with the name of the device directly instead of the UUIDs. Like /dev/sdaX etc.. in the first column
of fstab. Then when I rebooted with the SATA hard drive everything worked fine. Use fdisk -l for finding out the
device number sdaX. Hope this helps

(A quick check with hdparm -Tt /dev/sdaX also gave me higher buffered read speeds than with the IDE emulator)

Nop /boot are in the same partition,!
Ok I check with livedisk!! thanks!
