can't boot fs after I turn my "sata native" able in BIOS

yesterday，I happened entered into the BIOS，so I check the config and find my laptop havn't turn my sata native on. So I changed it from disable to able. Then reboot my laptop and find out that: when Loading Udev....Error occurs : can't find /dev/disk/by-uuid/0e32ffea-bce2-4754-8518-23d427b97774 and so on .......
So I root my laptop to try my Fallback Kernel .and it can boot successfull.
I try to disable sata native in my BIOS and boot my first kernel successfull too.
so I think it must be the "sata drive or moudel haven't turn on in my boot img.
so what Can I do ?

Poke around in /boot/grub/menu.lst, but don't edit anything until you're sure of what you're doing, or have a backup CD (and a backup copy of that file) somewhere handy.

Windows was made for looking at success from a distance through a wall of oversimplicity. Linux removes the wall, so you can just walk up to success and make it your own.

@dav7
it has nothing to do with the menu.list
the fallback img use the same location with the first boot img
and I find something via net says that the sata would do to this problem
who can help me~

Sounds like there may be a module conflict now that you've enable sata native (old disk controller driver is getting loaded instead of the proper driver needed now that you've enable sata native). Easiest way to fix this should be to...EDIT: follow the advice below about rebuilding the initramfs image

cheers,

Why not boot with the fallback-image, because as I can understand it works, and then reinstall the kernel? If you haven't changed any hooks I suppose it will while compiling get it right according to your BIOS setting.

Or you have already tried that?

You most probably have to include the proper module in mkinitcpio.conf MODULES and rebuild the initramfs (mkinitcpio -p kernel26) prior to switching to AHCI mode.

it's a quite simple issue: Run the fallback image and rebuild your initrd (mkinitcpio -p kernel26) and problem solved.

They say that if you play a Win cd backward you hear satanic messages. That's nothing! 'cause if you play it forwards, it installs windows.

@ALL
the bad news is : I tried to rebuild my kernel and after that my fallback came out to not work then.
the good news is : I google and find out that: SATA Native means"SATA NCQ" which have  to enable sata_ahci in moudles.
BTW:
I havn't rebuid my kernel successfull when I build from souces code .
Kernel Panic occours.
who can give me a simple .config for kernel.
my laptop is HP 520, intel 945,intel 950GMA,sata,combo,ipw3945abg,1G Core(TM) T2400.
